Twilight Princess and Super Mario Galaxy are reason enough to own a wii. Both games elicit pure gaming nirvana and unmatchable joy. Zelda is a smart well thought out experience which I gurantee you will love. Same for Mario Galaxy.
But this is a Sony meeting so may I also say- Sony has created some of the best new IPS this gen, HS, Uncharted, Resistance, Motorstorm, Infamous, MAG, LBP, WKC.
