The last time I heard someone talk about “exploiting” achievements was a couple months after the 360 came out. I realize there’s people who care, but I also realize there’s a lot more people who don’t care at all.
You buy small games that include a Platinum and then say it’s broken? Buy a bunch of 20-30+ hour games and is it still broken? I don’t go achievement/trophy hunting. I actually turned off the Trophy notifications. It was silly, finish a level, earn an achievement. I could live without it. It’s cool, but I’m not rushing to get every trophy.
I’ll say this: I wouldn’t spend a dime on the game(s) he played.
