I loved GRAW1. Never got 2. I played GRAW1 on my 360 online a ridiculous amount though. I had a blast with that game. A few friends and I were going to start a small little clan (in our neighborhood to start) but then GRAW 2 came out, and GRAW1 online sorta died down. Hardly any of us got Graw 2... Great games though.
Vegas was wonderful online as well. I didnt really like the single player, but I loved the multi player. It was top notch. I really loved the level up system.
