League of Legends!
 

League of Legends is a pretty fun game produced by the developers of DotA. I highly recommend this game to anyone who enjoys multiplayet, and tower defense type games.

It's absolutely FREE.

There are over 50 champions to choose from, all with their own unique playstyle and abilities. Each champion has a few different skins to choose from to fit your own unique tastes. Those cost actual money though.
