Trusty Bell is more impressive than LBP to you?
Little Big Planet looks more impressive than Trusty Bell to you
2 can play that game! hehe I am not gonna dog anyones preference and opinion to what is most impressive/best to them, but I think comments like the above are not really fair to Trusty Bell at all. The goal of Trusty Bell is to look like a classic cartoon and it does an outstanding job, both technically and artistically, of absolutely NAILING that target. It is very, very rare for a game to get close to the target they wish to emulate -- be it reality or be it CGI. I believe Trusty Bell is closer to its targer than a game like Crysis is to its (semi-reality) or Little Big Planet (CGI cartoon).
A for giggles, and since I love Trusty Bell and think everyone should appreciate it even if they don't think it is the best looking game, click for larger pictures:
Trusty Bell / Eternal Sonata (US) looks like a cartoon. That is not an exaggeration.
In motion it is even MORE beautiful--absolutely STUNNING. The animation as well as the "life" in the world are excellent and are on par for what I would expect from an animated movie. The convergance of technology and the quality of the art (and the art direction) are amazing.
Little Big Planet, while having some excellent IQ, is severly lacking in asset quality and art direction IMO. I think LBP looks good and is pleasing to the eye, but as a total package it has many holes whereas Trusty Bell hits its target dead center--it looks like a cartoon. LBP has some nice technology (as does Trusty Bell), but where they separate IMO is that Trusty Bell has fantastic art direction and asset quality across the board whereas LBP is really hit or miss in the media we have seen.
Of course if you don't like cartoons then I can see how Trusty Bell is totally unimpressive.
My personal list would look something like
Team Fortress 2
Trusty Bell
Battlefield Bad Company
Crysis
Oddly I am not a huge fan of cell shading. But so far I think Trusty Bell and TF2 are examples of games that picked technologies that have a very, very high IQ return and then have shown a mastery of the technology in regards to art direction and asset production. I love what Namco and Valve are doing with these games even if I am not a fan of cell shading--they have absolutely impressed my eyeballs. The games are pleasing to look at, even more so in motion. BFBC nailed one of my next gen wish lists (destructible worlds!) and then has shown some nice render technology and nice character cutscene animation. Everything seems to fit. And Crysis... the technology is great as is the general art. Just little things like seeing things like trees sway and their shadows, soft edges and all, moving cleanly across the jungle floor and seeing sunlight bleed through thin leaves and then whack--you shoot your tree down. A world you can interact with that is this detailed... beautiful.
My Honorable Mentions: Motorstorm (too many artifacts in the shadows, weeds, etc), PGR3 (aliasing), Viva Pinata (beautiful but just short artistically for my tastes), Lost Planet (kind of bland and unnatural animation for my tastes... until stuff blows up and then it becomes the best looking game out there), FNR3 (animations are a little stuff at times).
