They need to make a movie of Resident Evil 4. This is one of the very few games that actually gets your heartrate soaring! Numerous times I've chosen to pause the game, go take a break,{no coffee}, and wind down. Any game that can make you feel like you are in the room with the creatures is cool with me. God of War is another of my favorites. You pick up pieces of greek mythology on the way.
I've played resident evil 1,2,3, and am almost finished with 4. Nothing is cooler than turning off the lights and getting submerged in these games!
