As far as fictional, it would be a super cool unite to connect Splinterlands characters as soccer teammates and translate their stat block into the genesis league paradigm, so our assets can be not only dynamic, (like staking them in tower defence) but multidimensional and can exist across multiple game realities as fundamental parts of other games.
The systems seem so similar by description, like the same exoskeleton underneath, you could think the assets would naturally align as well.
