The only time the Zero Punctuation thread at GAF gets any action is when they do a Nintendo game.
This time - Pokemon White

Someone chimes in with this to defend trading of Pokemon only occuring in grade school or Japan
P.S. He forgot "college campuses" in the list of places where people actually have the game, however.

Tragically, at least as far as North American universities and colleges go, that's a fair point.

I wouldn't have believed that two weeks ago. I rarely see anyone playing a DS in public, but then I went to a library nearby and on the higher and more secluded floors; it was like shangri-la for nerds. Some people were playing on the DS or 3DS, and others were watching anime and reading manga on public computers.
also, pretty visuals are always awesome and increase enjoyment. That's not limited to video games.
gaf has this weird mutual exclusivity thought process that says you can have gameplay or graphics, graphics or art (

), graphics or performance.
The perceivable downside of better hardware is rising costs of game development. And sometimes priorities are shifted and you get a lot of inconsistency, like a game that looks nice but has crappy performance. Performance matters more for the actual game than the quality of shadows or whatever.
but yes, Mario Galaxy would be even more enjoyable with better graphics, and be less enjoyable with N64 graphics. It would still be awesome either way, but the visuals certainly could make it better.
I'd say most of people feel that visuals are beneficial, including the Nintendo fans that have been lying to themselves for years and just now champion a visual effect on the 3DS. At the same time, all them gifs of PS3 give a skewed idea that graphics are the most important thing, as do all the posts from pseudo-PC studs.
