Definitely, I do it all the time. It hurt back in the day when I didn't have much money. Nowadays if I get a shitty game, I can afford to feed it to my closet monster. Rawr, me closet monster, me eat shitty games and accessories!!!
Everytime i buy a PCE game its "blind buy" i try and find videos/screen shots if i can or a review but in the end i just look at the cover art or read the description of the game and "roll the dice".
