This idea is derived from the recent LOOT ecosystem and their derivative projects. The idea here with aavegotchi's is to incentivize derivative projects either thru grants or wearables sets or some other form of 'payment'. The reasoning for this is to engage community building beyond just minigaames.
An example derivative project could be one gotchi to claim a generative set of NFT ghosts which could then be placed in the realm paarcels in the future as a form of decoration.Or cacti wearable holders can claim some generative cactus NFT that could act as in game furniture as well.
Just a little idea to pop the cherry on my first proposal.
