If you’re looking for a quick game to kill a little time at work then this is not the game. Super Mario 63 ($FREE) is truly a complete Super Mario flash based game that is basically Super Mario 64, but in 2-D. It has all the levels from castles, floating pirate ships, ghost houses, water levels, underground levels, and even lava levels. If you play this at work you will get fired. The sound track is pretty much directly taken from Super Mario 64, graphics and game are actually really nice, and the author created new items you can use such as a water jet pack. There are save game files so you can keep track of your progress. What do you have to lose? It’s free, try it out.
