Kile, this is more of a version where you play the GM. You draft your players, set the lineups, pitching matchups. You give the computer (HAL) a general game plan (ie when to bring guys in, def subs, etc). But things like replacing injury guys is up to HAL. That is the part of this verison that really irks people.
You may want to look into buying the actual CD game, it lets you play online vs others. This version here is good, if you dont like the hassel of finding other to play, and you want someone else to do most of the work for you!
