Unfortunately, I've played games drunk, many times. I've played COD online a few times while drunk, and it wasn't too bad actually. I sent a couple of messages to the person who kept killing me as I was dying so many times, but other than that, I was OK. I was thankful I didn't think of putting my headset on.
Although, I've played games on my PC while drunk, especially the older medal of honor and call of duty games. I've been kicked from servers a few times because of how annoying I was getting. Usually though, the server admins can have a laugh with me, which is good.
