LOL. Cindy, you are hilarious.
Anyways, onto the topic. I LOVE fps games, though I tend to suck...... Eh...
Not all that into the retro alien games theme. And it looks too cartoon-ish for me. I like the realistic war games FPS, like battlefield 2142, and such. L4D is also a fave because people on there are actually interesting in playing with you as a team, with mics.
