Modern Warfare 2 (campaign) - 9/10
The plot is more like a "what if?" alternate universe, but it is very suspenseful and fast-paced. Had no real problem with the length of it. Took me just under 11 hours on Hardened. Any longer of a campaign, and I think it would have felt dragged out.
Modern Warfare 2 (multiplayer) - 5/10
It was phenomenal for the first two weeks. Then the Javelin glitch appeared, and ever since then the MP has been nothing but a mess of glitches and hacks that ruined the experience. Then the extent of just how overpowered the perks and killstreaks were became evident. It went from a fun time to the most frustrating experience imaginable.
Fallout 3 (including all 5 expansion packs) - 10/10
I can't say enough great things about this game!! The story is absolutely engrossing. The visuals are stunning (the march across the bridge to the Memorial at the game's original climax was EPIC!!!). The missions are immensely varied. Logged 106 hours playing through the game and its expansion packs, hit all the XBOX achievements, and ended up feeling like I'd lived a whole other life inside the game.
Batman: Arkham Asylum - 9.5/10
My only complaint about this game is the over-reliance on Detective Mode. The FreeFlow combat system is by far the most fluid, intense, and effective system I've seen in a game and sets a new standard. The story, visuals, and voice talent were all phenomenal. Can't wait for the sequel!!!
