The save depends on the number of things which should be remembered, and in DD that's a great number, unlike Diablo. Divinity remembers EVERY item which was placed somewhere. With the number of items in the game world, the ammount of information is extraordinary. Plus the realationships to each game characters, explored locations... So it comes to 20+mb savegames.
That's no reason for big savegame files <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
Ultima VII and IX savegames remember also EVERY item's place in the world. But those savegames are much smaller.
