FORT is a historical sim that uses random player debut, and just switched over to OOTP25. We are in 1993 right now, having started this version in 1980, and sim a season in just over a real life month. This is a dedicated group that has stuck together a long time (some members remain from ~ 2004), but be warned that means some of them like to talk a lot of smack. We have 20 teams, and three open - the Detroit Tigers, who are nearing the end of a run but are a fierce team; the New York Yankees, who are in the first year of a rebuilt; and the Chicago White Sox, who could go in either direction.
Here's us:

We have a bunch of house rules (like you get 150M, use it or lose it, every year) that are worth checking out:
