It wasn't just ps3 limitations, it was bigger because there was a lot of repeating of objects and such (called instancing, but not like it's used in games, it's several copies of one object to save on memory and performance.) It was the trade off of having a bigger zone, WoW did it too, but did a better job at hiding it, and with having much, much less detailed objects and zones. Yeah, the zones were bigger, but they were mostly empty areas that looked and felt a LOT like the same area over and over again. Lots of running just to get to a town that was exactly like the last one. I played 1.0, and the only things i really miss are the higher textures (characters especially, this one confuses me) and the ability to make almost any spell aoe or single target. The rest seems to get bandied about as this great missing thing, but it wasn't really.
