Our collection, or most of it. There's a 5-shelf bookcase with games for trade, and a smaller set of shelves with card games and dice games.
In the hobby (logging plays, researching games) about 12 years. For collecting interesting games, I remember looking at the Mindware catalog way back when, and picking up a few things now and then. I had a copy of ZERTZ early on, and I knew about games like Qwirkle.
We mostly play city-building/development type games with low player interaction, and some press-your-luck games.
Favorites are always hard, but Antiquity, Agricola, At the Gates of Loyang, and Magnate all come to mind.
We tend to sell/trade games that don't work for us.
I don't have any big must-haves on my wishlist right now. If I were to win a game, I'd probably pick #PARKS
