All of my games got trumped by Halo 2. 5. MechAssault 2: Lone Wolf. Friends played it, entered a competitive clan, and won money...but I passed it up for some dual wielding action. 4. Splinter Cell: Chaos Theory. One of the best games on Xbox, but I had to choose between super spies or plowing over people in a Ghost. 3. Ghost Recon 2: Summit Strike. The expansion to one of the best Clancy games ever. I bought it, but never played it because my friends spent all their Live time playing Halo 2. 2. KOTOR 2. Sequel to one of my favorite RPGs ever. I played through KOTOR so many times, this should have been a shoe-in...but got overlooked because there was no multiplayer. 1. Most of the Xbox 360 Launch titles. Until GRAW came out, I bought my 360 to basically play Halo 2 in 720p. Team Training with friends was always so much fun. I played a bit of PGR3 and CoD2, but Halo 2 has had more spin time in my 360. 0.5 The one game that really helped cure my Halo 2 addiction should get some mention. Guitar Hero 2 was the first game for PS2 that I've played since SOCOM: US Navy SEALS. Now that I look back, I feel bitterness toward Halo 2 for ruining gaming for that year or two. I missed out on too much. Hell, it kept me from starting up a WoW account when all of my friends were engulfed in it.
