FYI This isn't Robert, this is his better half writing this review! As a Sims franchise addict, I've generally stuck to the PC platform after the hideous previous attempts to push this onto the console. I got this game as I have a PS3 and had no games I wanted to play on it. So far, it has managed to suck a lot of my time. Even if you're a PS3 n00b like myself, the controls are quick and easy to master and the trophies are relatively easy to obtain if you're familiar with the PC platform versions.
The Karma aspect adds another dimension to this game which isn't available on the PC platform and the new Challenge Rewards to get new stuff for your Sims in addition to the standard Lifetime Rewards from the PC Platform.
So far, I'm finding this game really rewarding! Its hard now to choose between PC and PS3!
