Yeah, I was trying to be too smart. The worst that when I did simple prototypes, it all worked. But only when it was developed into proper functionalities, it turned out that I would either have to spend lots of time to streamline and balance stuff, add tutorials, explanations and I could still end up with something that didn't feel right or I could throw out some things and keep those that do work.
I'd still like to play around with some of the ideas that I cut from T4G. Just not now, of course :)
