I think everyone would like to see linked -something- during the APOC games. If it's linked tables, or linked BFG games going on that affect the "main" table. I think the narrative track would be a lot of fun and I know it might not be the biggest draw, but it seems really unique and those guys are all having a blast playing in it.
But if you make it overly complicated (by linking too much stuff) it can also bog down an already slower pace game.
