This concept intrigues me as much as it flummoxes me.  I've never played Pathfinder, but my brother did play the computer game you mentioned and he gushed to me about it.  It appears to me that this game you are planning to run is free form, and so won't involve all the dice rolling and math that playing Pathfinder typically requires, which I'd like, as I have no idea how to design a strategically viable Pathfinder character.

Even if my assessment is correct, there are still a lot of things about this concept as I am interpreting your Opening Post that confuse me.

Firstly, are our characters being Isekai'd from our world (Earth 2025) to Valykar, or from a fantasy world to Valykar?  Are our characters adventurers possessing their Archetype skills prior to being Isekai'd or do they suddenly find themselves with all of these new skills upon finding themselves at Valykar?  Are our characters all humans, or could they be other fantasy or alien races?

Secondly, it appeared to me that some of the Mythic Paths listed in that wiki are only available near the end of the game, such as the Swarm that Walks or the Golden Dragon.  Is it safe to assume that for the sake of balance (and being able to plausibly be able to work with other players) that these Paths are off limits?  Also, are you expecting players to have an Archetype and a Mythic Path, or are you expecting players to base their abilities off of one or the other?

Thirdly, your mention of all of our characters having superior speed and strength implies that everyone basically will already have fighter stats.  Do you think this will make characters that go for more of a wizard-like archetype unbalanced, since that character wouldn't have the usual drawback of being vulnerable in close quarters combat?

Lastly, since this takes place in a sci-fi setting, would characters use sci-fi weapons like laser rifles and energy swords instead of cudgels and bows like the Pathfinder classes would typically use?

As for the Isekai setting, the world you are in is Mer, the city is Valykar, and your original world is Earth, yes. :D

All good questions. The problem is I accidentally linked to the Archetypes and Classes instead of the Mythic Paths. Don't worry, ALL MYthic Paths are open, this is not a carbon copy of Pathfinder. Also, yes, you can use weapons of any kind, ancient/Medieval, modern or sci Fi. 

As for the wizard and spell casting characters being more powerful than others, well in real life, if we can call it that, yes, they would be, but not necessarily in this RP.

As for the Archetype/Mythic Path thing, you know what, why not have both? ::pepsi commercial::
