I haven't read all of the posts, so i'm not sure if some have mentioned these characters. Garrett is one of my favorite characters been waiting for a new Thief game for a long time. Kain from Legacy Of Kain, great character and voice acting is great. Same with Agent 47 aka Hitman. Eidos has some great characters. B.J. Blazkowicz, is there anyone that you had more fun killing Nazis with?
Here's a hint... look at my avatar AND my PSN ID (just take off "_Josh")..... still don't know? Click on the spoiler then!
