I found the world to be a lot smaller and less diverse than FO3's. Anyway, it sounds like the bugs are about as fixed as they are ever going to get, so aside from revisiting it for the DLC, I can't imagine I'll be spending much more time exploring the original game. Even with the whole thing installed on my hard drive (which do speed it up a great deal) we are talking about load screens ranging in the minutes rather than the usual expected seconds range. I just don't see that as acceptable for a modern game, especially one that requires loading so frequently. It was hard to be impressed by the Vegas Strip when it takes no less than four load screens to walk through the whole thing.
