Well, I've upped to Star Colonel and that may be it for me. 95 percent of this will eventually be available for retail, and I'm not seeing any major savings on most of it to justify getting it all at once through the Kickstarter. $20/25 looks close to retail for the lance/star packs. Double forces is a nice bonus, but I'd like to be able to choose two different packs instead of getting two of the same. The map packs and battlemats are the same price as the last ones.
I have to see if the leather-bound version of Legends is Kickstarter exclusive, if so it'll be my last add-on.
I think my 6 'Mech packs will be the Command Lance, Battle Lance, Direct Fire Lance, Fire Star, Support Star and Heavy Battle Star.
I'd love to get one of everything, but I'm not made of money unfortunately.
