75. Squarez Deluxe!
PC, 1998
Another great multiplayer game, but also great for single player too. I would play this at my mate's house every morning after getting dropped off there before school and after school before I got picked up. It was awesome, and I have it on my PC to this day. It's a bit like an advanced version of Tetris and it can keep me playing for hours. Getting an insane score is very satisfying in this game, as is slowly cramping up the space for your opponent in multiplayer. Just another great game, really. The basic mode is already fun enough, but the extreme mode is just plain awesome and leads to all kinds of tactical decisions.
