[General Discussion] Best review scale?

Over the past while I've been finding that I usually only play games that receive good reviews or are made by developers I like. Once I got my PS2 modded, I tried out a lot of games that I'd normally ignore, but found a few that I was genuinely impressed with, despite their flaws.

Since everyone values aspects of games differently, I figure the simplest review score would be out of three:

Buy it
Try it
Avoid it

I'm thinking of avoiding reviews entirely these days, and making my opinions on games based on previews and developer logs. It makes things more interesting.

Jam it back in, in the dark.
