This isn't about shooting people dead. This is about character development, negotiation, diplomacy. I will allow "Bound Pistols" meaning they last for 12 shots, every player once they enter will have only one.
Yuor from the FO universe, going to the TES universe. Sorry this isn't a guns-blazing RP, this is more character development.
No, I don't want a shoot-em up RP.
You're normal people who enter a portal to a strange new world filled with magic and excitement. You must either learn to live in it or find a way to escape. There will be a threat to the wasteland, once you get far enough into the RP, don't worry about daedra, be more afraid of the legion coming to conquer...
There's quite a simple answer to all of these, which seems to have been over looked by some? Instead of being wastelanders, going to Tamriel. (Which would make it a TES RP, not a Fallout RP.) You could have the players be from Tamriel, and travel to the Capital Wasteland (or wherever you plan on having the wasteland part be.) Then it will be a Fallout RP, and involve less TES and more Fallout. Since after all, this is going to be in the Fallout Fan Fiction area, it should mostly be primed on the Fallout Universe. NOT the TES Universe.
So simply put, have the characters be from Tamriel, and go to the Wasteland. Simple, no?
