Motorstorm is the only game I have so far (aside from demos of GT, Ridge Racer, F1 and Genji, with F1 being the only one I've kept).
It took a few goes to get into, but initial annoyances at it being way too hard soon gave way. The loading time is now my only issue with it, and it's not something I place that much importance in anyway.
I think the console looks ok, and I like how it's heavy and chunky. It just feels well-made. My only problem is how it loves to collect fingerprints and the curved top preventing me from using it as an impromptu shelf.
I still need to get the memory card adapter and a PS2 pad adapter (£30 for a second pad I won't use? I've spent enough); I've been told I really ought to get Fight Night also, but NBA 2K7 is looking likely to be my second game.
