I guess you don't realize that it takes someone to make this a game. If there aren't any programmers to create this game, there will be no game. And by the way, the game in the episode looks good because it's not the game in itself but just drawed.
hehe, you wont have it like in the episode... thats just impossible, but something that may look something like that, maybe... i think this game will be like runescape (you should try that if you cant wait...:P ).
