Have you ever created a "metavillain"?

[Ethandrul]

I just had an idea for an arch enemy. Imagine a priest who casts an augrey spell and learns he is in a false universe. He then learns of the concept of a GM as a master God and a party of adventurers who are secretly the people that the universe unravels around. Realizing that the odds are never really in his favor the villain begins to worship the GM and form a cult around him. His prayers catch ( me) unexpectedly at work and I grant them. Teaching him the importance of stats...feats...dice and Doritos. The new high priest of the temple of ME then crafts an unholy relic...a set of dice that are enchanted. Oh...and don't have all the numbers on them. He crafts new spells that cause out of game effects like cuse a player to use dice that aren't his own or to go to the bathroom at the worst moment. Would this be fun or silly?
Or both?

Seems like a truly dreadful idea for a serious game, Could work in a comedy game but it is not something I would enjoy as a player or GM. Be sure your players will buy in to the fun not walk out

I couldn't do it on the basis of realism.

See, I'm a nice guy, and a villain praying to me would need to basically turn it around and become a hero before their prayers were granted. And that's way too spotlight-stealing from the PCs for me to think it would make a good game.

Oh, and also, the idea is deeply silly. So there's that.

Well, I would definitely say it's "silly," but that doesn't make it not fun. It does, however, completely destroy realism in a way that is probably irreparable, so if you were going to make this one episode in a long-term campaign, I'd advise against it. In fact, I suspect that it you were going to make this guy the central villain of a long-term campaign, I'd still advise against it, since this kind of fourth-wall shattering "gimmick" isn't going to be funny the second time that it's encountered.

Speaking only for myself, I tend not to find metahumor very funny. I find it pretentious and lazy. If the only jokes you know are jokes about how bad jokes are, your jokes need to be really good -- and most people simply aren't that good. But your players are the ultimate critics. If you think they'd enjoy it, then by all means, have fun. You don't need permission from random nerds on the internet -- but by extension, even if all the random nerds on the Internet like the idea, that doesn't mean your players won't walk out on you.
