So I decided I'm getting a PS3. Took a while to determine that's what I want and not a 360 but I'm pretty sure. 360's got more games I want, but PS3 has games I want more, which is important since it means I'll end up spending less.
My brother's got a 360 and he's cool about letting me play it, but that's only a few months out of the year when I'm home from school. One of my suitemates has one, but he's kind of a dick when it comes to sharing (despite the fact that all of my stuff other than my computer stays in the common room, and he comes and goes in my room as he pleases). So I only get to play when he wants a Left4Dead partner.
But at the end of the day, I'm more about RPGs than FPSs, and so I can get over the fact that I've got a 360 dangling in front of my face without access to it.
