I didn't care for the Wii version. The GUI is messed up from what I remember. Also, they really should have not made any Metal Slugs after part 3. It gets extremely old. It should be Metal Slug 1, Metal Slug X (or two (but not both), since that seems to be the same game, except during the day) and maybe Metal Slug 3.
Metal Slug is best in extremely small doses, especially since not a whole lot changes between games style-wise.
