We've talked about playing with older folks before, but that's not even the best part of this story-- the best part, in my view, is the thought of two people discovering that they can do something they never thought possible. There is definitely an accomplishment and a thrill that comes with gaming (and this game especially-- taking out trolls is always fun), and it's awesome to think that these two were able to discover that.
I did a run of Dire Maul last night on my up-and-coming Hunter, and just like that Blackrock Depths run a little while back, there were a few newbies in the group-- we had to explain tanking and aggro a couple of times, and I had to use Feign Death. But even through just the chat channel, you could tell they were having a ball running through all the demons in the old elven city. That kind of stuff definitely makes me happy this game is around.
