Nah, I'm a pro, by now I better be. I've been through all this with my Ps2, like I mentioned, I know better than to continue to play discs after I discover circular scratches on them. My copy of oblivion just started to do that, when I knew something was up. I got it all resolved, not much damage, the third system, a feb of 2007 i believe, worked fine, like a charm.
As for console of choice, The Wii, because Nintendo is the single greatest game developer on the planet, they release consistently good titles every year, some of the most enjoyable, as well. Out of the 360 and Ps3, I dunno. They both have a shitload of awesome games exclusive to their respective platforms, I would've chosen the PS3 a couple months ago, but with several major developers jumping ship laely, and pulling exclusivity, it makes the decision that much harder.
