Are you bringing your games to Catalog?
Sorry for the late response! I'm pretty sure Catalog supports vouchers, so if there's something you want of mine that you've already paid for here just let me know and I'll send you a code for it.
The only games that will have features that aren't supported outside of Catalog are Generations and Shift, which are going to use Panic's leaderboard API like some of the season games. This API is not usable for non-Catalog distributions (which is really sad), but everything else will be the same.
