Anyone can make an app, and use the app stores to distribute it without the cost of manufacturing and materials.
However...making something like CR is still a daunting task. I have zero programming skills; the most I could do is use one of those app makers.
So...I am giving CR this last hope. Someone would have to research the plausibility of doing this, and someone would also have to program the game itself. I am and would be available for input on mechanics and physics.
I doubt I'll log on here for a long while, so if anyone wants to hit me up about anything, you guys have my msn and gmail; send me an email.
