The Flight Simulator might've been one thing, depending on who owned that game. The only other reason Youtube would suspend an account is due to behavior issues. If you were being nasty to someone, flaming/bashing videos, abusing the comment voting system, harassing anyone, that would also get you suspended.
Youtube doesn't suspend accounts to "be mean", no that's not one of their reasons. There's always a reason. Someone may have filed a fake DMCA or whatever it's called against you (it seems pretty common nowadays, I've heard of it happening before) and that got your account down. Someone might've hacked your account and was acting like a jerk to everyone and that got you suspended (or they could've closed the account themselves).
But if you don't want to get another account on Youtube there are other alternatives. DailyMotion, Yahoo Video, Vimeo, Veoh, Megavideo, and LiveVideo are just a few examples.
