Uhmm... I kanda agree with him (gotta love his rants and F bombs), but I kinda disagree with him. I've been buying a lot of "artsy fartsy" games on Steam lately, but I don't think they're pretentious, I think they're (mostly) awesome and unique.
Not only in the graphics department, but on gameplay mostly. Braid, leaving it without it's "artsy fartsy pretentiusness", it's still awesome and unique. Same with the similar and funnier The Misadventures of P.B. Winterbottom (ok, maybe the name is a bit pretentious, but I like how long it is). Shatter, maybe is not artsy, but damn it has some good graphics and the retro love of Pong clones is great.
The ones I would call "artsy fartsy" would be big names. Crysis is the first that comes up to my mind. Strip it out of its graphics and you have a generic shooter. Same with Street Fighter IV, strip it off it's water colors and you have... a great fighting game?... uhmm... let's try again... Okami... no.. it's still the awesomest game on Wii...
