i also got that email and was suprised in a good way, so i decided to buy rebellion from stardocks homepage not cus i enjoy that sort of games, but for the reason to sponsor the company. i think company's that has such a goodwill and really stands behind their software are rare, another company would just say "oh crap this game sucked, well who cares as long as we can milk money out of people" while stardocks actually gave us another game only cus the first one was a fail.
i do salute you (stardocks) and i will remain a paying customer to your company.
