I've been playing GT5 for... three years? now, and still feel like there's so much left to do. Granted, the A-spec events are a little on the thin side, but there are so many variables to be had by using different cars. It's incredible that even now, I can re-do a relatively easy race in an underpowered car, and get that feeling of excitement and achievement that I used to get in the 'early days'. And then of course, there's Arcade Mode: jump into one of your favourite cars from your garage, and marvel at the variety of opponents that it throws at you. Basically, for me there's no other game to compete with GT5, for what it offers. YET.
