I've played every Elder Scroll game (even Arena and Daggerfall) and I love them all, but there are some weird things about all of these games. For example, the way that corpses flop around sometimes. Kill something on the side of a mountain and sometimes you can't even catch up to it to loot the corpse. :)

And yet, of all the games I've ever played, Bethesda RPGs are the ones I find most fun to replay. I like Fallout too, but the Elder Scrolls are the best, bugs, weird physics, and AI and all.
