The Badderhackers just finished a 10 man team hack project of the game Monster Party and the whole thing is awesome, so you're quite a bit wrong about people not being able to get together and nail out something pertinent. Changes include new music for all the levels, a change in mappers, the ability to lunge, new boss behavior, bat range extended, and a whole bunch of other stuff. I didn't take part in the hacking since I wasn't around when it was my turn. It was kind of a tag team effort where one person would work on one level, another person would work on the next until it was complete, then one person finalized everything to put it all together with ideas from the rest of the group. I watched the first half and the end half take shape and it plays really awesomely. So that just goes to show you, team rom hack projects do work if you get the right team together.
