Hoo boy. I did not realise there was a boardgame thread here. I am a massive board game nerd.
I'm by far the one that enjoys them the most in my group of friends, though they all enjoy joining in when I set up a game night.
One of my friends refuses to play Game of Thrones (2nd ed), since he's never won it in the 70-odd times we played it, and some are hesitant to join in on a game of Twilight Imperium 3. Of course, TI3 is not for everyone.
However, I've been... collecting people to play with, so I now have enough people to split it into two groups. One group for 'regular boardgames' and one for the people that are mad enough to get into a 12-hour long game. Admittedly, the people in the latter group (me included) have the stamina to play two games of TI3 back to back. It's amazing. Such a great experience, every time.
Other games I play frequently include:
7 Wonders (with all the expansions)
Star Realms
Runewars
Spectre Ops
Descent 2
BattleLore 2
I've got a bunch more games, but those are probably the ones we play most.
