idea: release the bones of the game (the non-porn bits) as a standalone game then release the porn bits as a "mod" available through a third party service or idk github

if youre more of a manga person, the original manga also covers the entire story from beginning to end. minus timeskip stuff like super and daima. its very well paced as well

i love db!! i suggest actually starting with the Dragon Ball anime, then moving to Z. most americans start with Z and it gives them a warped perspective of the series (as its only the 2nd 2/3s or so of the original manga)
