Well if you do, then here are a whole swag of free 3D online games to fill up the time. I'm sure they'll occupy you for a whole of 2 minutes...at least.
Puki: The Swarm is a cute laser-shooting game. It's an epic tale (not!) of white round ball-monsters who try to eat you alive! Your only defence is a dual-laser with which to zap the little critters. There's also a shield you can use for a split-second.
Snowfight is another innocent game. As the title suggests, you walk around a fenced snow-covered field hurling snowballs to hostiles scattered about (including dorman snowmen).
Rifleman is for all you shoot-em-up fans. Set in WWI, you're a rifleman (duh!). You'll need to use the zoom function in order to nail those bad guys.
And who can forget Curveball (aka 3D Pong). I remember mentioning this on an earlier post wayyy back - but I really love this classic game. SUPER CURVE BONUS!
