As someone who has only been to one relatively small convention, I'm curious as to what games get played year after year at major gaming conventions. Are there any non-"event" style strategy games that are still played after their newness has worn off? Are conventions primarily for playing new games and games that require too much time and/or players for in-home gaming sessions?
I was in the GenCon game room for 3 nights. I saw all kinds of games spanning many genres, years, and popularity. Tons of Catan, Waterdeep, Dominion, and others. Basically if it is older than a year old and still recommended here...it was there.
Strangely this site knows what it is talking about, even if we get a bit excited about new releases.
Any game that people can open up a box and start playing in short order will have legs at a convention. Gateways work really well here. Add in some classics that always get played and you are then left with some newer games, but those are aided by someone knowing how to teach it. I did a recent Con report where I talked about if the game was Con friendly or not.
