If you like fighting games, and like programing you can collaborate in making a open source platform fighting game engine, and a game too later, that will have cross platform game with charters other games like Street Fighter, Mortal Combat, and Super Smash Bros.
So if your interested, we do have to make a fighting engine first, I plan to start from scratch though I did made 3 versions of a fighting engine I been working on. That may be useful to learn off of.
Here's one of them http://sandbox.yoyog...blitz-engine-v3
Message me and let me know what you think if your interested.
