For a first year I think the 360 did alright. Some would say "solid if not spectacular", but I'm not one of these guys
Anyway, I've been a bit surprised by the support from japanese developers. We got some crappy games from the usual crappy/average jp devs, but we also got RR6 (could have been better I guess, but still a good game), Dead Rising, and now Project Sylpheed. 3 games from publishers who did not support the Xbox or only with broken games. Considering how bad the Xbox games sold in Japan, and how badly the 360 started there, it's surprising to see these games, and even more surprising to see that these devs (not Square though) have more games to be released in the future. As a japanese games lover, this makes me very happy.
One thing I really disliked in the past year is how the vast majority of the game released had major framerate issues. I'm not a framerate whore like dark10x, but still slowdowns and heavy tearing are annoying. Especially when the game doesn't look *that* great for a next-gen title. What I saw in Leipzig and Tokyo thankfully seem to indicate that the next wave of title should be much better. I guess the 360 GPU was much more difficult to use efficiently than anticipated, but since it's a brand new design (compared to the Xbox or even PS3 GPUs who are essentially PC parts) I guess it was to be expected.
