I've been playing for 22 years now (damn i feel old

) and i buy more or less the same amount of games, although i've always been selective with what i get, buy what i like and rent the rest (god bless blockbuster

) and i found that there is a lot of trash out for sale that gets a lot of promotion, and some games that aren't, are better, so it's harder to find this few good games than it was 5 or 10 years ago (what did i just said

)
it could also be that you have found your style of games and you dont want to try other things (that happened to a lot of my friends :P)
