Theres only two things which I use as a guideline to buying a PC game: User reviews: such as those on Amazon (admittedly you have to weed out the ones posted a year before the game is even released), Gamespot or other similar sites. But usually its the negative reviews that have the greatest sway, as they often point out bugs or flaws. Try before you buy: I never buy a game without actually trying a demo first. If theres no demo available then I either don't buy it, or wait until someone I know has it. This is also the other reason I use bit torrent, if there isn't a demo I d/l the full game. If I like it I buy it, if not I delete it. Proper reviews have very little impact on what games I buy. At best they point me in the direction of a gamen that looks interesting.
