Super Mario Galaxy is among the highest reviewed games of all time, and alot of people consider it a masterpiece.

Zelda TP could also be considered a masterpiece.

It's safe to say that the Wii has had at least a few titles that are truely top-noch, and currently there aren't any games this gen (or last) that 'everybody' (or almost everybody likes) it seems all AAA and AAAA titles still have people who consider them to be overrated.
