Gamerscore -- however, a recent Official Xbox Magazine interview with Gearbox president Randy Pitchford has got us worried about our fellow man. According to Pitchford, developers who tweak their game's Achievements to make them a tad easier to obtain can boost sales of said game "by something like 10 and 40 thousand units."
Yes, Pitchford claims that there are 10 to 40 thousand people out there who purchase games based on their capacity to bolster their e-peen. That represents around $2.4 million being spent on making an inconsequential number slightly larger. Our faith in humanity wasn't just shaken by Pitchford's report -- it was absolutely obliterated. We're gonna go watch Rudy a few times until that faith is restored.
