Dani has gone to GenCon, a huge gaming con, a few times and enjoyed it. (He started going after Origins, a large gaming con, took a quality dive some years ago.) He asked me to go with him this year and I agreed despite its size. (It is, literally, an order of magnitude bigger than any SF con I've been to.) We talked about things I would need from him to help me not be overwhelmed by it, and he was fine with making those accommodations.
Then the schedule of events came out at the end of May and I realized that a convention an order of magnitude bigger than any I've been to also has a program an order of magnitude bigger than any I've seen. Even after Dani sorted the spreadsheet into categories and suggested some pruning mechanisms, I stared at that "board games" tab and kind of wilted.
But I don't need to find All The Best Games; I just need to find enjoyable games. So Dani made a pass through it for things he thought were interesting, and I reviewed his picks and gave him a short "no" list and a short "meh" list and said everything else was fine. (I'd already reviewed some other categories, including "spouse activities" (yes they have "spouse activities"), for things I could do while he was doing things I didn't want to do.) The general plan was to attend most things together, splitting only on these differences of interests. This is all very kind of him. We were going to mostly attend this con as a couple, which is cool.
Then he took all that data and went to sign us up for things, and... almost everything on the "A" list, both games and other things (seminars, concerts, brewery tour (ok that one was for me), etc) were booked already. He started to assemble a schedule based on the "B" list but it was hard and, anyway, it was the "B" list. He said this has not been a problem in the past, but this year is GenCon 50 and that probably has something to do with it. So we bailed. We'll try this another year, when he can show me his con in a better light and not be feeling "meh" already before even getting there.
