My personal opinion is that we don't need a graphics engine for ballpark details - a text base routine would suffice.
I started a similar thread here (

As a few here have said, I don't think we want the finances of the game overpowering what's happening on the field. Real world Owners and GMs have large staffs which take care of all the details - in OOTP it's only us, so it's really easy to get overburdened if what you really want is a baseball game.
