This topic is also close to my skills. but I'm usually not creating games, or just never finish them (I have 2-3 discontinued games on my pc)
They also free to use, and I don't want to make any kind of paid game (maybe some ad supported) beacuse in pony Topic I'm really afraid of Senior Hasbro's C&D mails. but always feel free to donate (and don't tell it to Senior Hasbro).
I'm usually creating native games for Windows/Linux, and sometimes for Android. Mostly 2D but I created some 3D stuff already (just not uploaded).
The other reason for the lack of games is that I'm not good at content creating (sprites, models, artworks, design, music, and others). And a lame content can highly degrade the game itself
