Here is actual buyer's remorse from the AC series.
Friend backed it. I didn't have to pay for a copy I helped him move in exchange. I got fucked in this deal
That game was actually super legit if you got good enough to hold your own on the JP servers where there was a lot of activity. Although that would've meant that you needed a JP copy of the game. Same deal with Verdict Day but it's not as competitive because of all the broken shit.
