The only problem is I need an idea that is very popular - I'm no game designer!
With what I have seen in Irrlicht any type of game is possible - FPS, Racing, Fighting. I am looking for something simple that everyone can play, so no complex game mechanics.
I also thought about making a game only available on consoles - a Hamster Ball game did well off the back of Monkey Ball.
I am open to any ideas, opinions, even MMORPGs (ala Gamedev forums!).
Thanks for looking.
