These people are serious about their darts.
I had lots of fun playing some darts and a lot of pool/billiards in my day. Something about being in an old fashioned dive bar and playing strangers.
But after a while some of the shine wears off. What I don’t like about those games is that, at a certain level, you almost need to play perfect. You mess up and the other guy wins. It doesn’t make for the most interesting of games. So I think it’s better not to get that good.
