While I somewhat agree with the definition, since it reflect what I had in mind, do we really need this ?
I mean, as NicWester said, just play the way you want, spend what you think you can reasonably afford if you want to, and that's it.
I'm pretty much a gold fish I guess but still, I couldn't care less about what other people paid. I just enjoy the game and drop occasionnaly a few bucks on it. Probably like Jedigunnie, I'm sometime in between Goldfish and Dolphin. More than $20 but never $100, too much for my butt and I would be uncomfortable spending more than the price of a AAA new game for some reasons.
