I just mentioned the same idea to Chr0n1x in the 10 requests thread

Any of us could easily write a game tutorial too, so it wouldn't be just me taking waaaaay too long to get things done. I think it is a really good idea though. The only thing we will have to make sure of though is to get the engine to a point where it can easily be used to make all those simple games and get any of the needed changes into the tutorials from the start (not a big deal, I do this a lot anyway :p).
We might divvy up the games and have each of us work on one and try to complete it with the fewest needed changes to the engine code as possible. If there are some things that would be better handled in the engine and are just simple changes/additions to the current code, I can merge them into the base engine and we can go from there.
Let me know what you think

You too Chr0n1x :p
