Anyway, so far I like:
- physics improved a little
- engines sound better
- everything 3D
- peeps walking on the track before you start
- no jaggies in the scenery (trees, peeps, mountains, fences, bridges, houses)
- aerial views of the mountain are stunning
- in replays, the cars are stunning, lighting is perfect
- no lag, no framedrops
- it's free!
- Ferrari
I don't like:
- cars don't look much better than in GT4 to the player
(no in-car view, not even rooftop cam)
- tire sounds (especially when drifting) is the same
- lacks sense of speed
- auto-gear seems slow
- overall lacks detail, it's like GT4 in full-3D (no flat textures for public or peeps, or trees)
