well what i would like to see in the game is that the player is allowed to make more bad choices such as was the case in the other fallout games. here there are almost only peacefull decisions. with bad i don't mean that they will be indeed bad for the vault. they can sometimes be very good for the development of the vault. what i mean with bad is the option to raid villages and raider camps or instead of letting new dwellers in to the vault rob them of all of their belongings if it benefits the vault and even to call an extreme decision to kill the new dweller and then it's added to the food bar just like in fallout 3 where the people of andale had to resort to cannibalism to survive. also there have to be bad sides to these decisions as well so i suggest that if the player attacks villages and raider camps often they may be faced with a counterattack way more powerfull to the normal raider attacks or if the player decides to resort to cannibalism to survive some people may not like that decision and leave the vault. maybe even add the karma bar. if you have the highest karma the luck of all dwellers will be +2 and iff you have the lowest karma the luck of all the dwellers will be -2.
