Hi guys
Would it work to make it a bit Wreck-it-Ralph-ish? The characters now they're from different worlds, but they don't act strange about it. Although in this case they don't know they're from "games" or roleplays in this case. The world could be a mash-up of some kind, smashing the world's iconic parts together into a small city like thing, were the characters just interact.
To help further explain this for all newcomers... (As I think this plot is settled.)
The RP is essentially a casual cesspool of any character you want to play as from any RP you have previously been in. These characters will travel through various different scenarios and setting alongside one another, it will be a casual sandbox RP experience that will allow players to play as and better get to know any character they have previously created.
As for the "plot" so to speak...
All of the characters are aware they are from different worlds, or at least they'll most likely realize it pretty soon. However some omnipotent force
(Blarzigord) is warping them through dimensions and throwing them into various situations for his amusement.
This is established more as a way to explain how the characters will react to different things... and as a means of all the characters actually being where they are. It's technically a plot, but there's no real depth to it... basically the omnipotent presence is using them as a means of killing time, they can't do anything about it and so they have no real choice but to interact with one another in the varying and progressively varied scenarios put forth by the omnipotent presence. (Eg. Café, Hotel, Desert Island, Medieval/Fantasy, Murder Mystery on a train, etc. etc.)
In other words, the characters know their own worlds, will have to adapt and react to different worlds... and the reason behind it all is that some God thought "LOL this will be funny" and threw all of these characters together.
That's about it as far as I understand it. There's no real underlying plot besides this apart from, presumably, small interactions and adventures that characters will get up to themselves in the settings provided.
In other words, casual hilarity and comic relief will ensue.
Edit:
Actually, I thought we'd just let the players choose that themselves. Most likely, I'll let my characters just be there with not much of a mystery, because the setting isn't the plot. The characters are.
Eh? So we're not going with the Blarzigord thing anymore?
Alright never mind I'm starting to lose track of what's going on myself. XD
