The Wii version of Metal Slug Anthology is great. If you were one of the fans who enjoyed playing the coin op versions in the arcade you will surely enjoy the Wii version. Playing with the Wii controller is interesting, but slightly annoying if you want to throw grenades as you must frantically shake the controller in order for you to throw a grenade. I preferred using the Game Cube controller as it gave the game play a slightly more classic feel. The graphics look good on the Wii version, just like you remember in the arcades tiny bits of blood and all.
Since the disc has all the Metal Slug games to date there should be plenty to keep you busy for a few days. It probably won't take you long to beat them all, but as a bonus there is a section you use points from playing the games to unlock various art and story boards. Fans of Metal Slug will want to buy the game right away, those new to the series will likely get by on a rental.
