Erika, Dave, and I have just finished a couple rounds of Jetlag Hide & Seek Across Tamriel! I think it went pretty well, Erika and Dave both had runs about an hour long, I'll get my run tomorrow. We did run into a small technical issue of the game trying to tell me where my group members were even though I politely asked it not to, so we'll see if we can get that fixed. I also think photo questions are too powerful in this game and after my run will suggest boosting the cost to two cards.
I do think calling it a 'medium' sized game is the right call and might adjust the interrogation page to allow some of the 'large' game questions
Anyway, it was fun and mostly worked! Hopefully we all want to do it again in future, potentially try it out in different games as well? I feel like different locations in ESO are a little too distinct for this, but maybe we'll see how it all works after Erika and Dave have had more runs to get used to the game mechanics and all the meta-level stuff
