I would guess that the only chance you have of finding interesting game reviews is by finding some amateur person or people who just maintain a blog or small website for fun. That's dependent on those people being smart and not awful, though, which would probably bring it down to a handful of blogs total. I don't really know any, but the type of thing I am describing is basically
http://www.actionbutton.net/. If you look at that it's just a well presented blog you can search and read reviews on. Now, I thought actionbutton was pretty cool once but I haven't read any reviews in a while and I know the guy who writes these as someone from selectbutton and he's OKAY but he can also be pretty irritating in a pretty typical internet guy kind of way. Also, the reviews can be pretty pretentius. So I'm not using this as an example of a shining success, but that it fits the format I would think that good reviews would be in.
I'd be pretty excited if there was a site/blog like that written by a cool person. Sometimes I take a look around but it's kind of hard cold searching for something like that, it's something you are probably more likely to find from sifting through forums because a member there knows the person doing it or is actually doing it themselves.
I've thought about doing it. I mean, I spend alot of time reading what other people have to say about games. I've probably spent a collected like 10 hours of my life just reading about what people had to say about Silent Hill 2, and they weren't even saying anything interesting and were mostly irritating people. However, I've been trying to cut back on that lately cos I find myself clamouring for reviews, or more likely, forum topics about things I am currently invested in and it's probably influencing my own thoughts on it too much. I find myself reading about a small piece of something someone else picked up on, and then adapting that into my own view of it as if I thought of it when I didn't even and probably wouldn't care about it if I hadn't heard it from someone else. That could be good or bad though, but basically I don't want to sit around reading reviews by critics and things people say who I don't even respect the opinion of. I mean, I wouldn't ask these people about it in conversation.
