While I play with random all in my skirmishes the vast majority of the time I feel like there are enough Gods and certainly enough Maps that I would appreciate having a way to name/save custom selections of maps, or custom selections of gods.
I don’t think it would be a high cost enhancement, and I think it would have some value. (Though admittedly more value for solo players who like variety rather than multiplayer play fans who likely have a god/map preference and don’t want random.)
