It almost looks like box could fit the expansion with a little re-design. The faction trays look quite roomy and might actually be able to accommodate new units. Those, plus a few new map tiles, are the primary space requirement for expansion? (I haven't opened mine yet. Perhaps i underestimate the space required for more cards, more cities, etc.)
Hi! I am sorry for the late response, but I was on vacation for 10 days and enjoyed some abstinence from the internet
Your post prompted us to re-check our design for Runewars. While some components from the expansion could reasonably be integrated into the existing trays, we find it impossible to fit the entire expansion in there. From a spatial standpoint alone it might be possible, but then we would have to give up some of the nicer design choices that are supposed to supplement gameplay.
This is at least our position at this point. Another designer might find a working solution!
