I think this is a excellent example of how we could add to the Fallout.
Having a city to explore was one of the things we all missed in the first two games, and its almost a must in any post apocalyptic story.
especially if one of the enemies were big radiated ameba blobs slithering around....dropping on you from broken beams above your head and etc.
I have read a few stories with those ameba-like beings just slowly going around, menacingly, until they manage to grab something , they would then slowly digest it inside themselves while from the outside you could still see the body decomposing....and bones of recent aquisitions.
They were resistant to almost all forms of damage, and their touch was like poison ( make it so that if player gets touched he looses AC little by little until he cannot walk anymore and Ameba gets him)
And there is an excellent short story by Damon Knight called -Four in one- it would be one of the coolest things if that would happen to player...it would so go along with those Ameba creatures....it would be sooo goood believe me.
Go read the story. its really good. im not telling!
well alright...its about small science team that gets on some planet...and main guy goes for scouting with three more. from the crew, ,.... and something happens...he slides of some small rubble onto funny looking piece of green turf and then wakes up inside this gelatinous creature...without his arms, legs, eyes, mouth....
And after a long time, after first rushes of fear and panic he senses that he is not alone inside the being.
Crazy story i tell you.
Imagine that happening to you suddenly in fallout.
And having to reach solution on your own he he.....if you read the story you will see that saving yourself from that would bring you some realy cool revards.... and it would force you to roleplay for a while in a different way believe you me.
