And I've been catching up on some games that I've wanted to play, but haven't been able to.
Just recently, I've beaten Gears of War, and Call of Duty 4, (I wish CoD4 had co-op. It was fun in GoW) and played Forza 2, NHL 08, and am going to be playing Assassin's Creed, and Mass Effect soon.
Just wanted to share some impressions.
Call of Duty 4: Wow, I love this game. It raised the bar for every shooter I play from now on. I no longer need a gun to go into a zoom mode where I can't see the gun anymore. I love the AC 130 level. It's so similar to the real thing. The ghilly level in Chernobyl is SO cool. Love, love love love love playing through this game.
Gears: Fun, and I've played to the end of Act 1 before with a friend, and played multiple multiplayer matches before, so I was pretty versed in it. Ended up teaching my step-brother quite a few things he hadn't paid attention to, like Active Reload, and Roady Run.
Forza: Hate it.

Just because I'm impatient. If I were a real car buff, I'd have a blast slowing down on corners, and driving carefully.
NHL 08: Great, especially if you play or watch hockey. Or enjoy the intricacies of a good team sport.
All in all: Love my 360, and I'm going to be playing it quite a lot in the future. Haven't touched my Wii since I beat SMG. <.< Kind of not seeing much of a point to have it, besides some game releases, like Brawl, and No More Heroes. I'm sure I'll play a lot more on it in the future, but right now, my 360 has captured me.
