Guys, I just wanted to bring it to your attention that Portal and Portal 2 (some of the finest videogames ever made, with a badass female protagonist and an incredibly compelling female antagonist) are currently on sale. You can buy Portal for 2 bucks and its sequel for $5.

Fair warning: Portal is all about, well, portals. Meaning that you jump around space a lot, bending it like a pretzel, while in first-person view If you suffer from motion sickness, that would probably be a problem >_>
