I agree with zero, in terms of graphics, those two titles, Tony Hawk and Gun, aren't what is expected out of the next generation, and all of my friends who have seen the screenshots released so far, agree with me too. I guess you can blame it to those other incredible looking games, like Elder Scrolls, or Gears of War. Well thats what you get out of cross platform games, and these two from NeverSoft being worst case scenarios since they're actually cross "generational" games. Lets face it most typical gamers are easily swayed by pretty visuals over gameplay first, and thats what leaves that first, lasting impression on them, about the game and system too.
The truth is, because of all the hype that both Sony and M$ have been spewing out, moreso with Sony (you gotta love Kutaragi's statements), and the promises that failed to be delivered last time out (Toy Story-level graphics with Ps2, remember?), gamers are really expecting way too much with this coming generation of systems, and yes, I understand were never gonna see "Killzone2 demo"-type graphics on the new systems.
So back to the topic, lets just put our faith with Neversoft, and leave the developers to their work, although a little criticism from the gamers themselves wouldn't hurt and should be welcome, both games aren't finished yet, and who knows by the time they release we could be in for a few surprises.
