I have two coupons on steam for endless space. One is for endless space emperors edition (all content of ES game). The other is for Endless space Disharmony (which means, I think, it requires the base game to play). Both are steam coupons tagged as 'tradable, not marketable.' I assume this means i can give them away, yes? PM me if you want me to gift you one of these coupons. BTW, you must have a valid steam account for the system to allow transfer of coupons. - elana
Edit: When >> steam puts games on sale, its often 75% off. << If you wait, 75% off is better than 50% off, yes?
