Wow, you've based your opinion on some trolls on Facebook? Really?
Game-wise the WP7 phones have a small edge over competing platform because of it's XBOX Live integration. This allowd you to communicate with your friends, dress up your avatar and score achievement points on the Live certified games. Some of the usual suspects are here: Angry Birds, Puzzle Quest 2, Fruit Ninja, Plants versus Zombies, Bejeweled. Then there are some cool uniques like The Harvest, GeoDefense, IloMilo, Tentacles.. The selection is not as bad as the troll cave on Facebook make it appear.
When I compare my experience with my WP7 (Samsung Omnia 7) to my previous Android Phone (HTC Hero) a half year after purchase, then the WP7 wins hands down when it comes to games. Remember how little game Android used to have, and the quality of the games was terrible (1.6 and early 2.x period).
