Okay so this isn't me asking about survivors, just giving additional material for whenever they do release. And I know the devs will adore this idea.
So similar to the Rimworld idea where you can put in custom characters you want to see in game, except you can't really. You can just increase the chances of seeing certain NPCs. Well in this case you will build NPC's imagine kind of a backlog of characters you can play as so you can boot them up and play with them without remodeling them and all that, redoing the traits.
Now here's where it gets interesting. What if we pushed that one step further and say you're playing as Jim Jones, but you have Sally Davidson created as well and you want to see her in the game? Well you would have an option pop up and bam Sally Davidson is now nin your game. But lets take it even one step further again, what if you want her to be related to you or another NPC you put in the game? I feel like once NPC's are ready and fleshed out and all that good stuff to implement this. It would add a whole new dynamic to the game. Another layer if you will.
Side note: I know some of y'all will say this will make the game to easy and to that I say, not necessarily. I mean you can abuse any feature. But if you want to balance your game, just create a balanced framework.
That will be all. Now time to sit back and be praised for what an amazing idea this is and how I make the all time best suggestions! Or ... You know get told it's a horrible idea and then go eat cake due to sadness. lol
