We had to go a slightly different route for our figures:
http://www.planomolding.com/content...&lineid=4&groupid=18§ionid=64&partid=234#
11 of these are pretty full, with our figures (inventory at the bottom), and I think enough space once we complete wave 6 (only one set in hand, another complete set is still being sought, along with a 3rd of the commons). I have two more empty waiting for future waves. The larger figures are stored with our terrain. 6 crates that we picked up from Container Store (can't find a link to them). The crates contain:
1 - large green terrain, cards (in a CD holder), rule books, and dice towers
1 - all other green terrain
1 - brown terrain (with large figures also)
1 - grey terrain
1 - road, ice, flag bearer dice
1 - castles, lava, trees, misc
the crates stack, and are easy to manage for building a map, and picking up when done.
Inventory:
5 - master sets (we don't count the 6th as that belongs to littlerwis and littlestwis)
3 - sets of master set figures
2 - of all uniques including gencon exlusives, except flag bearers
2-6 sets of all commons (through wave 5)
1 set of all wave 6 (waiting on 2nd heros and 2 and 3rd commons)
2 - castles
3 - lava, ice, and 4 road (thank you Markwars for the 4th)
1 - of each flag bearer (haven't a hard time stomaching the extra cash for 2nds of them, but I am sure my OCD will overcome common sense one of these days and I will do as I keep saying I won't)
I think that is it.
