I'm sure the bg maps were hard to render for the small teams they had back then.Infinity Engine also has smaller maps and started the entire process. I do like the engine otherwise. It is my favorite edition of AD&D.
On even slightly more modern hardware than when it came out, I think it could handle giant maps. By 2007 or so, there were PCs that probably could have stuck together all the world maps from BG1 into a single map - though that'd probably ruin the pacing/abstraction of travel time.
The FRUA engine used tiles and sprites which saved on memory while IE used pre-rendered backgrounds in a 2.5D environment. The IE did use all the cpu/gpu/RAM that was available for the time. It was a decision to switch from tile based maps to pre-rendered. Anyway, I'm just disappointed in the decline of crpgs as a whole.
