Is it suddenly not a good game, because you're playing it a year later? People are weird.
That is ALL too common my friend. Not just that, but because a game (or movie) doesn't have HD or the best graphics doesn't mean it's not a great game. My god, when I first saw Star Wars A New Hope in the theaters in the 70's, I was blown away, and the movie IS AMAZING even today when I watch it in the original glory.
Time goes by, but that doesn't make the game (or movie) any less of a game than it is now. But gamers seem to be a pretty finicky bunch.
