Well I was going to play Dark Forces, but Steam had Dead Space 1 & 2 for 75% off. I've been waiting to play Dead Space for a while now, so that got moved to the front of the queue.
Although, uh, unfortunately I wasn't aware that the game didn't have a first person view. A third person view works great for a game like Banjo Kazooie, but it's just so awkward in a shooter. My character takes up 50% of the screen. I hope I get used to this soon.
