Sounds like an entertaining hobby.
A guy I know messaged me over Facebook today and asked if I want to partner with him and his friend for making a game. Judging by his interests, he means a video game. >_> I'm screwed. I agreed to try to help, but I doubt I really will be able to.
It depends on what kind of games and what you will do. There are RMXP, games used with programmation languages(C,C++,Jave etc...) and homebrew games.
