I grew up in the 60s and 70s playing board games with my dad and friends and card games with my grandmother. (http://www.boardgamegeek.com/geeklist/30477
) Games fell off the radar in the 80s and 90s but I'm happily back.
Two player abstracts (with luck at a bare a minimum, if any) are my preferred favorite, with cooperative play against the game (LNoE, Pandemic, etc) being my preference with a group. My wife is grew up in a family of Chess champions and is very picky on what games she'll play with me. (I have yet to beat her at Yinsh) She doesn't like games with puzzle elements to them, so I play a variant of Mega-Fjords with my right-hand man at work on a regular basis.
Our daughter and her fiance are big gamers as well, making trips out to see them an all-but guaranteed good time.
I'm also a long-time thrift store junkie. I've bought some games just to be able to take pictures of them to post on BGG for the GG. Now that I've earned my avatar and über-geek badge, that has slacked off considerably.
My collection is largely of games that have interested me, games that I could earn photo-taking GG from and/or are from my childhood. I'm not a Collector; I don't care so much what the condition of the game box, I just want to know all of the pieces are there and that it's a good game.
