I subscribe to both PC Gamer and Edge gaming magazines, it's where I find a lot of smaller games that would have otherwise gone under my radar. As for reviews close to a games release, I'll just check out a few random youtube reviews and get a general feel from those reviews combined, listening to 1 or 2 people is never really a good thing as they can be bias without realising.
However, if I'm interested in a game, I'll just buy it anyway and try it out, if it's on Steam, theres no hard in refunding after an hour of play.
