[Suggestion] Backstage Pass / Season Pass
Stardock, please consider offering a "Backstage Pass* / Season Pass" if you plan on continual DLC's.
* a larger package purchased to support future developments to the game (ala a "season pass")... similar to the philosophy behind "beta-access" and "Kickstarter", but post-launch. Personally I'm not really fond of the term "season pass", and think "backstage pass" (as in "backer") is not only more applicable, but also more inviting.
