Rails as a type of terrain that subway cars, trains and mine carts could ‘stick’ to, only allowing them to accelerate or reverse along said track.
Electricity from any source spreading out over a much larger area in water
A BigDog or WildCat style robot that runs on a UPS, functions as storage and can be folded away for storage if empty.
A construction option for building wooden bridges out of logs or planks. Better yet if a more advanced option borrows from the palisade/garage door code to make drawbridges
The ability to use nearby lava as a fire source when crafting
Also, if lava can make the surrounding tiles hotter, would it be possible to have a placeable air conditioning unit or space heater that functions in a similar manner?
The ability to use more than one water purification tablet at a time for the purpose of purifying large volumes of water
Trap option: Pit full of acid.
The ability to handcuff zombies or NPCs to car doors or railings
Maybe a ‘knocked-out’ option for NPC ‘corpses’ that has them res after a while, like non-pulped zombies? Could come in handy for later, or if you just want to be the sort of one-eyed-two-horned flying purple people eater that saves his meals for later. Since the NPC ‘corpse’ could be put in a trunk and driven off–though they’d wake up and escape eventually. To kill them for good I’d imagine it as simple as doing enough damage to pulp them, smashing their body or good old fashioned butchery.
Somewhat related to the above. It would be GREAT if zombies attempted to feed on fresh non-infected corpses. Hulks had to have done something to get that big, right?
More ‘cave life’ so to speak, so that basements, subways, mines and caves could warrant some jackhammer’n. Mole mutant or chud conclaves, fungal pockets or flooded variants of subways that spawn sea life for fish PCs.
The ability to start a vehicle construction from a suit of powered armor and/or powered lifter. The end result being a cockpit that fully encloses the pilot ((entered via the ^ menu))
Battery hungry ‘parameter defenses’ like electrified plating for vehicles. If combined with my earlier suggestion of constructable bridges a clever player could make a boat house with electrified moat
Huge thing, probably not going to happen but it would be great if in winter the ground got covered in snow and ice. Without snowplows winter could really inconvenience players
Nearby rotten food lowering morale from all the odors it gives off and non-mammoth sized insects it attracts. Would be neat if it raised morale for those that could eat it though, I’d image it would be like if you constantly had pie cooling nearby to saprovores.
New conversation options for NPC followers ((Since they’ve gotten a lot better with all the work devs have been putting in)) Like loot restrictions–i.e. don’t pick anything up, only pick up food, don’t over burden yourself etc etc.–or the option to tell them what to wield and wear provided they trust you enough. The option to train NPCs in much the same fashion they do you would not go unappreciated either.
Peer pressuring NPCs into taking drugs or mutagen would be awesome. Especially if good or bad mutations modified their willingness to follow you accordingly. Don’t expect most people to watch your back if you turn them into a horrible ooze monster.
NPC only traits that effect how well they’ll get along with you. These would be biases based on gender, appearance, bionics, mutations or even stats.
The option to nickname NPCs. “I’m going to call you Skipper from now on.”
NPC gangs that hole up in buildings or block off parts of the city. Very well equipped but not initially hostile. They could demand the player trade enough items for safe passage or even given him “Do this or Else” style missions. Maybe if you do well enough they’d give you gang colors to fly --like an armband or bandanna-- that lets you roam their turf unaccosted. Since profession traits are becoming a thing maybe gang members/drug dealers etc could chose to spawn in an area like this from the start and wearing a badge would be shoot on sight shenaneggins.
I’ll think up some more later…
