Elebits - A very good FPS with original ideas, overlooked by its childish look. If the controls were more polished this one would had been excellent.
MLB Power Pros - A great baseball game, probably the best in the system, also overlooked by its childish image. The series is very popular in Japan though.
Order Up! - A great cooking simulator. Very fun and easy to pick up and play.
Pro Evolution Soccer - It takes time to get used to the controls, but once you do is very satisfying. This is a great example of a new way to play with the Wiimote, unfortunately it wasn't as popular on the Wii.
Silent Hill Shattered Memories - Don't know if overlooked, but this is an excellent game, one of the best on the system, and more people should play it.
