[18+] LFP for one of 3 ideas

I want to try and get back into the swing of things for a game I'm running for friends, and I've decided to try and run a game to get my thoughts moving. The three options I had in mind were a Naruto game using some D&D 5e homebrew rules or potentially OVA, a more modern/sci-fi game using a D&D 5E mod called Fifth Age (best comparison is Ghost in the Shell, I think), and the last would be a game in which the players were monsters/mutants of some kind escaping from a lab (not sure what system I'd use for this, but it's likely a homebrew another GM uses). Games would be text only, and would largely be theater of the mind with maybe some basic maps. If you have any interest/questions/ideas, feel free to ask/share! Notes:  Games would all be text-based, though if a player wants to use a mic, I may allow it. Also, I am not kidding about the 18+ tag, these games would all mostly be for the lewds. GM's time is EST

Naruto RP, for some reason, has always been immensely entertaining. If this comes up to something concrete, I'd be interested.

Yeah, trying to figure out how to handle jutsus and chakra is the roadbump for that one.

There was a d20 Naruto game out there though, surely that could be inspiration on how to handle jutsus and such?

I actually was part of a Naruto 5E game that used a system I liked that I want to modify, but another major issue is scale of power. Like... the way I feel like I have to start the game the jutsus need to be nerfed, at least for a time.
