Brad's ridiculous flakiness with playing games wouldn't be so unbearable to listen to if he would at least just cop to being a flake. His weird insistence that he will play games, that everyone knows he won't finish, only for him to not finish them and then get pissed at people who expected him to, is one of his worst aspects.
Also, it's not the game's fault if you disappear from the game for a few weeks and then come back and forget what happened. I get that that's not fun to see everything in context; but that shit is on you.
