How many shit games have you purchased over the years?
How much time did/do you spend trying to convince other people to hate it to?
I mean I used to be into gaming a lot more than I am today, mainly when I worked at Gamestop. I had every console and I played most games the week of release.
But I played some REALLY bad games, poor controls, terrible graphics, too long, too short, poor story, no real direction...etc. But you know what I did? I traded it back in and never looked back. I might have a 5 min conversation with someone on how bad it was. But I didn't go out of my way to make sure that no one ever purchased it again EVER! Nor did I berate people for wanting to buy it, "Oh you picked up Alien vs Predator... what are you an idiot, so bad! I bet your friends call you Baddy McBad."
Just go... wash your hands, and never think about it again.
