PCGames.de published their review of The Sims 3, giving the game a score of 89.  Can’t complain there, a B+ is always good – it’s how I got by in high school 😛  They list a few pro’s and cons and state that it’s pretty much the same game as TS2 but that it’s nearly perfect:

The Good
– accessible Sim- and building-editors
– smooth character animations
– lifetime achievements make you want to play over and over again
– wide variety of character personalities
– city-exploring is great fun

The Bad
– only a few accessories
– inaccurate chain of command
– camera view still sucks
