I like RTS's and JRPG's. The latter is my favorite genre of game. That about sums it up.
Well, maybe not, but that's my major disagreement. I thought that he had some amusing and serious points until I realized I wasn't sure what he _did_ like in a game. So he likes originality, strong plot, and maybe character development? Okay, but he won't allow for long cutscenes. There goes, say, Metal Gear Solid, one of my favorite series ever. (He didn't hate on MGS4 as much as a lot of games, but I did disagree with him on the subject of the plot. It _isn't_ that complicated and ridiculous if you really sit down and play the game and maybe have a friend who can explain a couple things, and although you may be late to the party, you can play it without playing the others. I did, and it got me hooked. Someone shout out for Ocelot always managing to win.)
He also won't go for anime style games, so that eliminates a nontrivial chunk of the Playstation series of games right offhand, including some very good, original, and interesting games. (He'd probably hate Chrono Trigger -- anime JRPG. For shame.) Every time he reviews a JRPG, say The World Ends With You, he always prefaces the review by saying how much he hates JRPGS. Seems like he kills his opinion before it even gets formed, there.
So okay, it seems he likes more realistic, 'western'-style games with lots of originality -- a la Psychonauts. Not too many cutscenes, the AI has to be superb, and there should be no semblance of grinding needed. Also, he seems to bemoan most adventure games that don't have a 'sandbox' world where you can go anywhere; at least, I remember him bringing it up a lot.
I'm still trying to figure out what he wants, short of every game being as weirdly off the wall as Psychonauts and Portal. Great games, but we can appreciate games that aren't like them, right? He takes the flaws a little too seriously; maybe if he'd lighten up a bit, he'd like games. But I guess since he's paid to play them, he'd get jaded after a while. Though I do find it strange that his praised games have also included a game-from-movie (Spiderman) and generally just sandbox games that probably have not much plot but allow for silly swinging-around fun. While that's great, I've always marked it as one of the least important aspects of a game. Just my opinion.
Also, on a last note, I wish he'd review more things I've heard of. But that probably trails back to my JRPG issue here.
And Super Smash Bros. Brawl was a darn good game.
