To be honest, Dr. Mario 64 is just about everything I expected it to be. It was obviously an effort by Nintendo to get a game out for the month of April, and get it out quickly. There have been virtually zero upgrades outside of the four-player versus modes, which lends little reason not to go back and play SNES version which featured both Dr. Mario and Tetris. If you're dying for a multiplayer puzzle game that you can play with three friends, then Dr. Mario 64 is well worth it for around $30. Otherwise, I suggest sticking with The New Tetris or the well Pokémon Puzzle League. Dr. Mario 64 is more or less Nintendo's way of using Mario's name to sell a port of a very old game. This doctor's Ph.D. expired long ago.
