Resident Evil 4: Wii Edition--The Short and Simple Review
RE4: Wii Edition is, importantly, not an original game. It was first created for the Gamecube a few years back, and it is now hitting its fourth release. Consequently, Capcom has had plenty of time to enhance the game.
There has been no new material added to the game since the Playstation version, but the Playstation material has received a graphical update.
All of the original aspects of the game that made it so great in the first place are in tact, and are made even better by the great control scheme that is exclusive for the Wii. The controls feel natural after minimal time with the game, from the point-to-aim shooting to the slashing for the knife. Consequently, RE4: Wii Edition is simply more fun to play.
Some have pointed out that the difficulty drops because of the better controls; while this might be true, the difficulty level is still high enough to keep the player on his/her toes (try professional mode for a more thrilling experience).
All in all, RE4: Wii Edition is the best version of the game to date. It gives an extremely satisfying experience and offers plenty of reasons to play the game again and again. (The score I gave the game is not based on prior versions; rather, I scored it on a stand-alone basis.)
