all I could say was WOW!
I had graphics set on full max for my the computer I use and wow! Some great detail for a PC. Swimming thru the water was awesome, I actually caught myself gulping from time to time!
I beat the game in 3 nights though! Wasnt happy about that.
Then I made a trainer for it (its a form of cheat) turned on God mode. Then went and jumped off a few high points. Tell ya, I found myself pushing back in the chair and my legs pushing on the floor! I mean thats how immersed into the game the graphics made me feel!
