I mentioned on another thread that just the difference in load times would have almost been enough in itself to justify buying Gt6. Adding that to the simplicity of the entire layout helps even more. This may be a small thing to some, but to me, it's a huge improvement. In Gt5, while waiting on a race to load, I'd always have to wonder if my satellite internet was messing up or if my playstation froze up, but most of the time it was just the slowness of the game.
The improved load time is real nice when we've got family and friends over taking turns doing 2P battles and everyone wants a turn. Everything works so slick and then changing cars and settings is so much easier too. Giant step in the right direction.
