Narrat Game engine looks like someone wanted to make RenPy as easy as the Adventure Game Engine for Windows was when it was released. The engine looks like it was made for people who wanted to write their own novels with minimum coding experience. They have their own easy script language and a plugin for the visual studio code which makes work easier. The additional thing to release ready for desktop and web is that the engine and games itself can be integrated into the website, maybe someone will use it to make their own ChatBot in an adventure style? Maybe this will be a disadvantage but the games look like the chatbot on most of the sites. But there are always some sort of sacrifices, and maybe in the future, there will be the possibility to change the style to another like with the RPG mode in this engine. Let's hope that the engine and its author show us more good material in the future. There is even a game jam for this engine! Links Website:  Narrat Download:  Installin...

Engine build as fork of the Cocos2Dx, which means that it comes with most of their functions. It is slowly developed by their team but in the end they are trying to make something good. It does not come with the editor so it is up to you to take some. The engine let you develop games with C++ and lua as scripting languages. It let publish games on Linux, PC, android and even on Xbox as the UWP APP Links Website:  Axmol Download:  Github  |  Installation guide Community:  API  |  Github  |  Wiki  |  Discord  |  Reddit

Another retro engine, but this time limited to one platform and not the genre. It was created for making roms for first Nintendo handheld. Due to block programming it is easy to make games. Due to possible export in from for the device so it can be run on it. But due to enhancements the limits were removed and users can made bigger games than 32K. In the end it is nice engine for everyone which gave ability to made games for handheld. Due to nature of the engine it has predefined genre of games, but they can be connected in one. So nothing can stop you from making your own zelda/pokemon/castlevania gae in one.

RPG Maker in open source version. Thanks. Solarus was created with the idea of open-source engines for homebrew Zelda games and thanks to this it has its own niche. If someone looks for the small easy, portable engine that helps to recreate action-adventure games from the NES era on steroids that's it. Solarus is great for this and more. No one says that it is limited only to that type of game. Due to easy Lua scripting language development is easy for most people. The portability is good enough, the engine easily reads the quest pack created in the editor but it needs to change thinking for gamers, like in most open-source engines. It lets you publish even on Nintendo, but first, it is needed to have an NDA signed with a developer license. The engine is really nice and worth trying.

Looks like another engine for corpo coders, or students from the previous decade. It looks clean and ready. It can be used as the main engine and also as the library for another app which can made things easier in some cases - android app. Due to being based on Kotlin, it gives all java features, even the rapid prototyping due to the nature of JVM. It is small and looks like one project for simple games. Devs are showing on the website features with the code, so users can check the complexity and approach for that feature.

The framework was created for making mobile games. It uses Lua as a scripting language over the C++ engine. Which guarantees that the end app will be efficient enough on most devices. Links Website:  gideros.rocks Download:  Version Community:  Forum  |  GitHub  | 

It is just another good framework, where you can do everything. Fun fact, it was one of reasons which helps the popularity of C# and DotNet in gamedev, due to problems with XNA on other platforms, developers started to port it with the Mono Framework. The project started as Mono.XNA and ended as MonoGame. Mono from the other side was widely used in Unity 2.X. Now after many years it is still good foundation to make various of games, but it has it's own problems like support of newer consoles and DX12 libraries. But in the end, if you are .Net developer looking for making hobby game it is very nice package to look.

Another project for those who like 3D especially Blender, Armory3D is build arund it by independent developer. It has Haxe as scripting language and nodes so it should be good Unreal alternative. Due to be build with blender integration it can be used as additional showcase for the engine and it's main features.

Engine from era before Unity and Unreal where everyone build their own engines. Now it evolved to gemeral purpose engine and is free except of royalties. For some people it can be outdated due to not using DX12 and Vulcan but they are solid in their work. They are free but with 5% royalties. If you want to look into the source code there is GitHub sponsorship and possibility to check this.

So it was one of engines which was develop to help bringing Disney games to the world. It is made for 3D developing but due to its nature connected with python language as scripting it is possible to made games easier. So it is another less known engine but still has many strengths.  Which could be good for enter into the world due to hype for AI and easy learn the scripting due to python language.

Happy New Year Created by game development teacher with two things in mind, first to be easy for learning programming, second to be modular so you will use only this what you needed. It starts with C as best example for creating games in old times but now have bindings for many languages. It is a framework, you need to have your own ide, follow instructions in their wiki . They support many platform due to OpenGl backend. License for the engine is Zlib. Links Website:  Raylib Download:  Itch.io Community:  Wiki/Github  |  Discord  |  Reddit

The engine which is a synonym for Visual Novel in FOSS world. It was made for it in 2005 and still rocks in their genre. It is made with python. Now like in Godot there is two version one for older projects with only bug fixes and new version 8. Because it is made for VN, and only for this, it is easier for artist and script writers to make games in it. On their forums you can find tutorials for writing and how to make everything from idea to deployment the game.

Personally, it was my first attempt to make game, because in high school I learned pascal on the IT lessons. What do we have here is engine which connects the old, very simple and friendly, language (Pascal) with never version of programming paradigm - Objective Pascal - and it is optimized so you no longer need to add the Assembler to make it quicker. In other words if you want to feel like guys who made games in last decade of the XX centaury but there is small fear of complex from C and C++ you can use this engine. I see that it evolve through years and you can work not only on 2D games but 3D too. And on PineTab/Raspberry PI so it is nice to learn main things from the programming and practicing it. The small con for the engine is the script editor is needed to use due to lack inside of the engine.

If someone think that SDL is too low level and pro(grahmer) thing for him. There is other project which simplifies most of things connected with 2D development. It has it's own communiti and is still in active development besides that someone could think that it is too easy. Some people say that it is grown mainly due to C++0x generation but in real it was clearly designed to be easy for newcomers and some of the design decisions are clearly connected to this. Like in SDL this is something which let you made your own engine. And it is good due to all easy things, there are many bindings for other languages nad platforms.

Another framework on the list. One of the oldest and used as the base for many games and engines. If someone choose this must be ready for very hard work due to low level programming and doing most of things from scratch. but for the cost of hard work it will give you very nice product with really good foundations for future releases. The project is done mainly in C and C++ but have bindings for other languages and is ready for releasing on many platform, but it need more testing than most of other game engines due its nature.

From developers to developers with LÖVE. In real it is really nice and easy to work framework. Lua as the scripting language could be old but it is really easy to show the concepts of the gamedev. In this software you have very good documentation and helpful community. Links Website && Download:  Love2D Community:  Forum  |  Documentation
