Having to spend more actual money, instead of in game money, to get different cars and tracks I wanted on the latest Gran Turismo sorta sucks. Plus things like the sound, collision damage, and system of car customization hasn't really improved that much.

When you combine with it the fact that track surfaces don't really change under race conditions as they should, cars still don't experience things like brake fade, and Polyphony still insists on having 8 slightly different versions of a car instead of actually bringing in different cars, it becomes a let down.
