Without the monster I mean.
Think about it, refugee, raiders, moral choices etc etc.
And obviously less weapons/bullets/food.

Huh?
If your implying that this is a fallout 3 rip it's not. Granted it haves the same struggle of human/specie survival among other groups, and before I go further fallout 3 is a great game, My favorite or at least in the top 3

Although...
Fallout 3 haves a whole other universe for gamers, and more importantly (that I hope they emphasize in the game) there was no real experience/feeling that told us "we are to survive!" I think I Am Alive will touch down on this very well.
