Not only do they offer less free games than PSN, but they offer WORSE games than PSN. Halo 3 needed about $12 worth of DLC to play with the other 5,000 people online. They also gave us Assassin's Creed II, Gears of War (not exactly mad about that one), Fable 3, Dead Rising 2, and Crackdown, just to name a few. Do yourself a favor and go look at how old and irrelevant those games are. THEN go look at PS+ and see that they offered BF3, Uncharted 3, Borderlands, Borderlands 2 (again, just to name a few), and see how much newer, more relevant, and better games they offered.
Anyone with a brain could've figured out Free Games for Gold was a half-done (if that) cop-out and rip-off of PS+ that Microsoft wanted just to shut people up. Let's not forget they announced two free games during E3, Assassin's Creed II, and Halo 3. Not only do they only release one game every 15 days (on top of a few free games at a time on PS+), but it took them MONTHS after they announced it to release Halo 3.
I didn't even like PSN for multiplayer back on PS3(i thought it was boring and the community overall isn't very skilled IMO) but even I can tell you LIVE isn't that much better than PSN. Only reason I even had LIVE is my friends had it.
