In China, I’ve seen Sims Eight In One, with all eight expansions and the original game. This is over 7 gigs I think.
I have PGA 2000 by Sierra Sports and the install was about 2 gigs. I have added over 50 add on courses and the game now takes up almost 9 gigs.
I’ve still got it, and yup, 6 CD’s! If you edited the the movie bits into a feature you’d have a better movie than Phantom Menace and Attack of the Killer Klones combined.
