I enjoyed GT3 and I plan on buying GT4 when it comes out. For me, it's really down to eye candy. Sure I like passing cars and winning races, especially the Rally ones. But for me what keeps me coming back for more is the amazing graphics. The reflection of clouds and trees on an Aston Martin or the glare of the sun off a windshield. The graphics are what keep me interested after I've bought the cars, etc. -Troy
