Best of 2010
Sadly I haven't had the opportunity to play Alan Wake and NFS Hot Pursuit. I snagged a copy of AW last week, but I won't be able to play it till January since my 360 is currently in another state. Seeing as I had to limit it to 10 games, I couldn't include all the games I really liked, so here's some props to Splinter Cell Conviction, Singularity and Darksiders.
The list won't be complete if I don't give a special shout-out to Halo Wars. Even though it came out on 2009, I only picked it up recently and, frankly, it has consumed me. If I could put it on the list, it would be very near the top.
