I started my own league before I'd spent much time on the forums, absorbing some of the terrific ideas people around here have had. So OOTWBB started in 2003, no prior simming, no particular theme, just a new league for a bunch of people I knew from other non-OOTP leagues that hadn't played a fictional universe before.

Time Warp is, as far as I'm concerned, one of the best ideas out there. 45 years of simming, recreating baseball history with fictional players (including ancestors of forum members) before going live for owners.

In the KBL, Kieran (kq76) started with a unique theme, but no prior simming. I don't think the presence or absence of prior history to the league makes much of a difference for the quality of the league. It's all in what you want to do with it.
