Well, since interest is starting to pop up I'll propose some more stuff to you guys; tell me if it's too outlandish or too strange for the scenario, all right?

For the pseudo-stat system, abilities only come into play once a deity has taken a character under their wing... so to speak. As in DanMachi, the 'interference' of a deity is necessary for stats to rise, which is in turn based on experience gained during fights and the like. Artifacts can also be used to fill this role, but only for the user thereof.

There is no such thing as HP/MP/SP here; instead there's Str, Spe, Mag, which should all be pretty self-explanatory. This won't work like a regular tabletop where rolls and everything are put into play; instead, characters can use them to gauge how strong/fast they are relative to the past. Monsters don't have stats - rather, text context will be given to the abilities of a monster and their strengths.

Humans won't be the only race in the RP; elves, dwarves, beastmen, elementals, draconids (lizard-esque humanoids) and fey all exist within the world (along with various other things that may or may not exist as NPCs/enemies). 

The local residents of the universe don't know that things like stats are derived from a game. They don't have things like that in existence.

Just because a god is "evil" in their old pantheon doesn't mean that they are in this universe, and vice versa. Who knows, Orochi might be a chill dude to hang with or Aphrodite might be secretly plotting to take over the place.

(This confirms nothing, by the way. Just examples.)

On that note, deities don't have to take the same form they traditionally took in out world. I'll leave how that is interpreted up to you guys.

A universal language does exist to make things easier for everyone. Let's just say it's English to save time and headaches.

Once a response rolls around I'll get to making forms and preparing for release.
