It seems there’s still some confusion about what Tower of Druaga: The Aegis of Uruk‘s OP means. Is it a hint as to the real nature of the world: are they all actually just playing an MMORPG? I think that’s a brilliant idea, but unfortunately I’ve decided that it’s nothing more than a gimmick.
You probably want proof right? Go watch the OP again, and pay attention to the texts that aren’t credits.
Had a go? Still no idea? Well, let’s take a look at the following screenshots:
If you don’t have at least some rudimentary knowledge of Japanese and seiyuu names (or the Wikipedia page open), what’s going through your mind right now is probably “Just fucking tell us already!” If you do, you may notice a number of funny things about the texts in those screenshots.
The books in the first one all have interesting titles. From top to bottom, they are: “Druaga Daily Conversations” (basically a language book), “Druaga Encyclopedia” (which you can’t see in this screenshot) and “The History of Meskia”.
The other screenshots all share one thing in common: names. More specifically, the names of the seiyuu who voice each character.
Now what do all these things tell us? Quite possibly absolutely nothing. On the other hand, I think what the OP does is show us who the characters really are in this world. The characters have their seiyuu’s names attach to them, to show who the characters are played by, and who they are really in this world. It is not, as some assumed, indicative of a world-within-a-world setting.
I’d love to proven wrong by GONZO though. The setting of a world-within-a-world should be far more interesting than a straight up fantasy.
