It depends on what you like. Marios Tennis is usually fun to pick up & play.
Wario Land is a definite if you like Mario/Wario adventure games.
I’ve never been much of a Telero fan, but others seem to like it.
Nesters Funky Bowling if also good, however harder to get.
I guess my favourite would be the puzzle games like Panic Bomber, V-Tetris and to an extent 3D Tetris.
Theres also Virtual League Baseball, but if you don’t like Golf/sports games then maybe its not for you.
Probably some others I can’t remember. Look at the main website for a complete list of VB games, however some of those games are rare/impossible to find.
