I remember when I first bought Balder’s Gate (very excited), it was a 4.5 gig install across four CDs. My computer’s entire HD was 5 gigs. Well, guess I’m not playing that then.

Most of that was badly compressed sound files though. The rest of the game wasn't that big since it didn't even have 3d.  


You could also opt to do the minimum install but that would require you to swap out discs constantly depending on what locations you visited.
