Nothing beats a good ol' game of Starcraft.

Straight up, this is one of the most classic strategy games you will play. It barely ever gets old, and when it does, you only have to take a break from it for about a week or two until it rejoices to its best playability. With literally thousands of custom maps still in the making, you cant run into the same game more than 5 times unless you want to. The community is still largely active, so you will always have someone to play with. It is quite satisfying to go on a computer killing rampage all by yourself and come out the victor.

A must-buy for anyone that loves the RTS genre.

The graphics are good, atleast considering when it was made. It is also only using a 2D Engine, so don't get your hopes up after seeing Company of Heroes.

The Campaign is quite boring if you have the same attention span as I do.

The Multiplayer is legendary.

And, the price is very low, only costing about $20 Canadian for Starcraft and Starcraft BW, and both Strategy guides.
