Hmmm, I love Oblivion, because you can do pretty much anything, and I am addicted to the Dark Brotherhood, because... Erm, because I like killing the NPC's.
and Fate, because of the cool weapons and monster's and Dungeons, and the music
and Fable 1 is pretty good when I used to play it, because of the Demon Doors and stuff
and then Sims ... 2? I forget which one. Anyway, yeah, I like that one because I like building the houses, which is pretty much the only bit I like
And last, like Destri said, Starwars, Rebublic Commando because of the Graphics and guns. Haven't played most of them for a few years though because we never owned any of them besides Fate and Oblivion, we just played them at our friends house.
By the way, while Oblivion is on the XBOX 360, Fate is on PC's only; I downloaded it on my mom's computer, so.
I mostly like RPG's.
But yeah. Oblivion rules!
