Wii Sports amazing party game, Rayman another amazing party game, zelda great hardcore game, and Red Steel below average FPS (concept is good, if you want a good FPS actually on the Wii go for call of duty, it has great sensitivity). Overall, I believe the Wii is a great improvement over the previous generation of games. The graphics are decent, and they will get better once developers really begin to use the systems power. The wii has the ability to look better than any Xbox game out there because of the horsepower. Will it be HD graphics no, will it look good that is subjective and I think Yes.
Overall, everyone who game to my little wii party today (10-12 ppl in all) LOVED the Wii and are now thinking of purchasing it themselves. My neighbor after seeing us play it, actually left my wii party and came back with a Wii (he bought it from a friend who got two for 325 dollars...do not ask me why he paid 75 dollars, whatever).
