Legend
I wouldn't look to Wick as some kind of template. There are a thousand Joh Wick movies out there that never got buzz to get sequels.
More pointing out it started out small and grew from there.
You can also look st various game studios doing something similar eg Paradox Intractive, Bioware, CD Projekt Red.
D&D has been inconsistent with its editions, games, movies and is still fairly niche.
