Adventurer
Many years ago, I did play in games run by a DM/GM that everything was lifted from pop culture. We’d adventure through something from the Curse of the Azure Bonds PC game, something from the Shannara series, Robocop 2, and so on. We had fun, but after a while it got old.
That's my fear. I think this sort of technique is great for a one-shot or a single specialty session in a longer campaign. If it becomes the whole game though.... Like you said, I could imagine that getting old in a hurry.
