[[WMG: Penny Arcade, PVP, and [=MegaTokyo=] are all part of the same universe]]
''Penny Arcade'' and ''Webcomic/{{PVP}}'' in particular reference one another fairly frequently and ever since Scott Kurtz moved into the Penny Arcade offices in 2010 the amount of references and stylistic similarities have only increased. ''Webcomic/MegaTokyo'' and ''Penny Arcade'' have made a few references to one another in the past as well, with at least one nod towards ''PVP'' in ''[=MegaTokyo=]''. Additionally, all three webcomics started within two years of one another (which isn't really evidence of any connection, per se, but makes for nice synchronization).

In this model, all three webcomics are really part of a single continuity where there is NoFourthWall or at least a very, very weak one (hence why characters so frequently get killed only to return from the dead in all three). This is, in fact, an acknowledged fact within the ''PVP'' webcomic. Additionally, each of the creators ([[SufficientlyAdvancedAlien Sufficiently Advanced Authors]] of course) has the capacity to enter into the universe physically (as in Jerry/Tycho, Mike/Gabe, Fred/Piro, Rodney/Largo, etc.). Some of the characters are [[MediumAwareness aware that they are in a comic strip]], such as the characters of ''PVP'' and possibly Gabe and Tycho) while others are completely unaware, such as (most of?) the characters of ''[=MegaTokyo=]''.

Also, for some reason, only Gabe and Tycho are actually aware that they are Sufficiently Advanced Authors, whereas both Largo and Piro are completely unaware of this fact, perhaps due to the fact that Fred Gallagher appears to have another avatar running about in the universe (mentioned in a ''Penny Arcade'' strip located at Sakura Con). Other characters are aware of this as well since although Scott Kurtz does not appear in-universe in ''PVP'', Gabe and Tycho and the staff of Penny Arcade do.

Yeah, that's confusing. But what good EpilepticTree isn't?

* Additionally, because Gabe and Tycho are the only authors that both are aware of their nature and are known to be creators by the world at large, this may explain why [[http://www.penny-arcade.com/comic/2007/9/26/ Gabe's birthday is an international holiday]] [[http://www.penny-arcade.com/comic/2008/9/22/ that puts Christmas to shame]].

* By extension, other web comics that might be a part of the shared continuity are ''Webcomic/TheWhiteboard'' (whose characters cameo in ''PVP'') and ''Webcomic/AppleGeeks'', which has a long-running crossover with ''[=MegaTokyo=]''.

[[WMG: Gabe is unknowingly a wizard from Literature/TheDresdenFiles universe.]]
This is why computers are always breaking down around him, and Tycho is constantly bitching about him putting off a computer-killing electric field. Clearly Gabe's latent wizard talents are making him a WalkingTechBane just like Harry Dresden.

[[WMG: Tycho's desire is to become God]]
This may be an instance of YMMV, but please bear with [[AwwYeAh me]]. If his heart's desire is enough to [[BeyondtheImpossible damn Jesus to hell]], the only possible way this could ever happen is that he could only do this by becoming God himself.

[[WMG: Rain-Slick is a prequel.]]
Rain-Slick is a prequel to the main Penny Arcade universe. After the turmoil of their previous lives [[spoiler: and the end of the world, Anne-Claire builds a better world for them]], one where they get to indulge their greatest pleasures in gaming and where nothing horrific lasts for very long. Rake Guy watches over them all as the reader. Not so much a WMG as heavily implied, but there we go.
