[Six String Guild]

Hi all:

I was a big Earl Weaver Baseball fan back in the day and have been looking for something like it ever since. I actually bought OOTP probably over 15 years ago but for several reasons, was turned off by it, mainly because they didn't have real players. On a lark, I looked up OOTP a day ago and it sounds like they do now PLUS all of the customizations I am looking for...I think. Below is a list of what I want to do w/ my game. Could someone let me know if OOTP 19 will allow me to do the following?
1. I want to take the best players from the past 40 years and make a fantasy/fictional league of 30-36 teams (depending on the number of players I come up with that are "worthy" lol).
2. Can I have more than 30 teams? Can I name them anything I want and pick a stadium from history?
3. From what I read, it sounds like maybe I can do this but it might be complex? How hard is it to do? IF so, is there a thread or webpage somewhere that walks a person through how to do this?

One more thing, if I decide to buy, should I buy it on Steam or from OOTP themselves? Any difference besides price?

Sorry for the questions. I've done some research and I can't really determine from what I've read and watched if this game gives me what I want. I'm looking to recapture some of that Earl Weaver magic, if not more. I'm ready to buy but I just need that extra confirmation. Thanks everyone.
