I'm doing a bunch of shifts for Privateer Press at AdeptiCon this year. Last year, I think I did a couple of shifts, but this year, I am doing more. Yes, it cuts into my con time, yes it means I do less events, yes, it means that I may miss out on a lot. On the other hand, I do love the game, and really enjoy watching new players pick it up and get excited about it.
As an added bonus - the fewer games I am playing, the better I feel about how few of my models would actually be done in time for AC this year.
