I refuse to buy the system until I see a game that demands the purchase of the console. I'm not sh!ting any of the PS4 games released or near release games, but none these warrant a console purchase.
I am a 33 year old male single gamer (by choice) who could buy either MS or Sony systems or both and WiiU if I wanted to (don't need to resort to credit either), but I'm just frugal by nature.
That doesn't mean I don't spend money, I do when it warrants it. For example, I decided on buying an R9 270 for my computer 3 months ago. Playing Dark souls 2 at static 60FSP and 1920 by 1200/1080p and it looks sharp, I can buy indie/3rd party games on Steam while I wait for the PS4, XBox One, WiiU to mature into something worth buying.
