On the whole i like it alot. Guden already pointed out the larger gripes (where to me the top half connectors (av & 802.11) really stand out as they just make the unit look unnecesarily cluttered). Another one would be noise, especially when the console is just sitting there charging your wireless controller through the play and charge kit (fans keep spinning here, which feels ridiculous). My last gripe is live download speed... here we are in the futuristic year 2005 with multimegabit internet connections and multiple 3+ghz cpus and wait hours, while a measly 500 megabyte download blocks the whole system...
PGR3: This one rocks. It is PGR2 and then some, especially on the live side of things. Nice graphics, sound, blabla... What stands out is the sense of speed, especially on 720p. All the blurred fast moving details make this the most believable console racing game yet. Talking of speed, loading times are an issue (at least to me) though. Of course there is a lot more data to be read from next-gen discs, the loading times on retries however, make me wonder... Besides i found the game to have issues when inspecting gamer cards on live. This led to three crashes for me so far.
PDZ: Haven't put to much time in it yet. The scale of some of the locales did impress me though.
GWE: Just played the demo but it sure is an addictive sucker. Kind of makes you wonder whether video game evolution has always been for the better...
