My way to see how good a game really is...
Ya' know, in the past, I've bought a game or thought one game was better than another based on the opinions of other gamers/peers/forum chatter. And some times, I played a game I really liked and er one else said it sucked, thus I didn't have many peeps to play wit. A friend of mine told me that the best way to see if a game is great is to say screw you to the boards of Game-Informer, Games Spot, IGN(especially) cuz the forums have loads of haters and fanbois to skew your perception. That's the 1st step...
2nd, go to Metacritic for a sum of all reviews, don't be fooled by a 100% or 10 ratin' cuz a game may have high marks and only like 100 reviews compared to game that has a slightly lesser score but it's based on 1000 reviews.
3rd and finally, check the sales, yo. If Metacrtic and that other site that's like metacritic(?) say the game is decent and it's sold like a bazillion copies in a decent amount of time, that should be another indication that a game is worth your hard earned money.
That's how I buy a "good" game. That's also how I see if I like a good game or do I like a game that actually sux.
That's how I've been doin it for a while, is there a better way?
