Nothing would please me more than having Half-life 2 right now, but Halo showed me that more than just Half-Life could do completely immersive, entertaining and frenetic sci-fi action with a great plot and characterization. Half-Life does some things better, Halo did some other things better, specifically the characterization of the person you play as, I never felt like I was Gordon Freeman because he never speaks about anything, you can only infer from what other's say, as Master Chief I knew I was the end all, be all of mankind's survival(another reason that Doom QUICKLY lost its appeal to me). I look forward to both of these games, as they brought me back to FPS's after a long hiatus of intelligent and interesting FPS's with great single player modes that made me want to know what happens next. When Half-life 2 comes out, it will get as many Kudos as GTA:SA and Halo 2.
