I'm a Steam gamer -
Welcome to Steam - and via Steam I play Counterstrike, Team Fortress, Portal, etc. Steam handles the online sales, online delivery, and online play of games to nearly three million gamers like me.
Let me suggest that OOTP look into OOTP 9 becoming one of those games, and before someone comments that games like OOTP 9 wouldn't work on Steam be aware that both Baseball Mogul and SI's soccer game are both successfully part of the current Steam catalog.
Getting access to that many gamers has a lot to be said for it.
