I just picked this up a few weeks ago and it is very fun.
I joined an international multi-gaming clan last winter to help improve my Smite game, and now spend my time in the Overwatch section. I fear I am by far the oldest member of that community and only hint at being in my 40s (lying!) That said, I keep my actual age hidden, which works fine. I've been gaming a long time, and prefer to game instead of watching sports or cable reruns... with an active clan, it's a bit like going to the pub after work.
Overwatch has been far and away the most popular game of late, it is really fun, and very well done team shooter, and reading reviews I decided to jump in. Worth it! It came out of Beta last April.
So if you Overwatch on PC, I'd love to find some more skeptic-folks to play with (especially secretly older ones!) Maybe join the same clan for team games.
