Right. Gamers are some of the most pretentious muhfukkas out there. A 2 hour movie, regardless of quality, will run you 10-15 bucks on release day in most theaters and 15-20 for blu ray launch. Simple math wil tell you that a game more than 8 hours easily compares to that and games these days are at times, cost just as much, if not more than your average movie to produce as well.
Being that their interactive, I don't see the complaint of a "short" game not being worth their full original retail value, unless the game just sucks. Not to mention seeing as there's so many solid games out all around, I don't see how any grown up with any time constraints and responsibilities need every game they play to be 20-30 hours long. I suppose that's fine if you only plan on playing like 4-5 games a year, but hell, there's usually 3-5 games dropping a month that I'm at leastl highly interested in trying out, let alone playing thru to completion or owning.
