I’m sending this to my DM, who is Mexican and currently running an Asian folklore inspired game.

When the DM does it we usually notice because he’s normally quite talkative, as DMs tend to be. When a player does it we might not notice for five minutes…

More levels does not, by itself, mean more of anything else. In one system you can get fifty different skills, features, traits, abilities, etc at each level and in another you get one attribute point increased by one at each level up. It’s one of those things that is absolutely meaningless without the context of a lot of other information.

That said, for the joke, Asian games tend to use a greater number of levels, either with smaller increases in power or they just don’t cap anything and let the numbers get bigger and bigger with little or no functional difference as long as you’re fighting things scaled to your level. A little stat boost every level then a special power after ten can be the same as one level where you get all that without the other nine congratulatory dings that don’t really mean much.

“DM, are we on drugs?”

There’s also nothing saying the dog is going to be any good at it, but I’ve seen a few humans do worse than I’d expect from a Chihuahua so I guess it would be better than nothing.
