Binary Compressed Save System, Save Entire Dynamically Generated Worlds! ♥ Rama

Three questions:

  1. Is there a way to offer a proof of purchase to get updates as they come, without waiting on Epic updating Marketplace (which has been disastrously slow recently)?

  2. Let’s say I keep updating my game, add new enemies, weapons, stats, etc. Is updated game going to be compatible with old savegames ?

  3. Same as #2, but also when updating engine ?

Thanks
