i'm still scratching my head wondering why it spanned 3-4 CD's???
4 CD's is merely 3 Gig. That's not even ONE DVD <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />. Baldur's Gate wasn't very big either, and that was four (or was it even five?) CD's.
Besides, most of the space was taken up by the graphics.
2D-graphics requires a lot of space, due to the fact that you have to save a lot of images/move etc. I'm not sure exactly how they work, but they require a lot of space compared to 3D-graphics.
