It's August 2015, and to follow on with the success of last year's #RPGaDay event, David Chapman at Autocratik has created a new list. Each day in August, I'll be posting my "answer" to that day's topic.
I don't recall when I've ever played in a session more than four or five hours long. That said, if I did, it would have been in my teens during the summer. We'd hang out in my friend, Shane's basement and play whatever we were up to at the time. Those could have gone 6+ hours, I'm sure. Lame, but that's my answer.
