Two Ideas I'd Like Help Deciding Upon

I have two roleplay ideas that I’m split between. Whichever one gets the most interest I will elaborate upon and make an RP out of.

1. My first idea is about a roving band of warriors in a medieval-esque fantasy world who have been inexplicably bonded to each other. As in they are literally incapable of moving a large span distance from each other and if one dies they all die. I know, this sounds kind of ridiculous. But I have it all planned out. The story of how it happens is pretty good in my opinion. The RP will begin before it happens of course. If this RP happens it will be a team effort pure and simple. It will also be continuously ongoing until it breaks down and dies or my peers and I believe it should end. I also acknowledge that this idea isn't even remotely original, but I've been itching to be in something like it.

2. My second idea is about the survivors of humanity during an apocalyptic event on a human colony light-years from Earth. The general basis is, during a civil war between two vastly different factions on a colony that lost communications with Earth years ago, an alien virus that seems to affect both organic and machine struck. The story revolves around the survivors inhabiting a remote military prison whose only captives are prisoners of war. At some point in the story they will be forced to leave said prison, and face the new world filled with techno-organic monstrosities. They will most likely be searching for a way off the planet at first.

So, which one do you think is better? I will accept neither but I'd enjoy a reason. I do acknowledge they're not nearly my best work. Also, keep in mind these are just general outlines, whichever one is chosen will be vastly expanded upon.

I like the 1st one. I suggest reading The Legend of Nightfall by Mary Zucker Reichert (I probably butchered the spelling of her name). Do not let the cover of the book fool you, it's not a romance. Anyways, that story (which is a surprisingly fast read) has the same kind of element of people being bonded together as you just explained and might help you expand ideas you already have.

It's probably different than what I have planned. I'll check it out though.

I'd be interested in this first idea. I have a character I would actually like to see in this kind of situation...

She really doesn't like to be around people. XD

What do you mean by "medieval-esque" exactly?

I'm leaning towards the second only because I have an insatiable Fallout itch that has yet to be scratched. And it seems Fallout-ish to me. Both ideas sound good to me and I'll most likely join whichever one is posted up.
