That they sold a pack of SoaSE with all the addons in it, so you paid more for the rebated pack, than just Rebellion alone? Despite rebellion being stand-alone and including all the games and addons?
So yeah, the stardock pack included SoaSE 1 / Diplomacy / Entranchment and Rebellion each for its own price with rebate /50%. Despite buying Rebellion getting you all of the above already by default. The price was also, hilariously, not rebated. So you paid 25% more than you would have needed. .. just found that funny
