Just a few random suggestions.
Just wanted to share some of my thoughts, hopefully see one in game at some point. :p
Here goes, take it or leave it, it's only harmless suggestions, and if I've "stolen" someones idea(s); I'm sorry, I don't mean to take credit, I'm just agreeing with you!
ALSO, if this should be posted elsewhere, tell me so and I'll take your hate, apologize and try and correct it.
Threaten enemy to drop weapon/items/bags/clothing, or just plain surrender. Some bandits/people would prefer this method, to save time/stamina/ammo and potential bruising.
Most un(der)armed people facing a desperate wastelander with a rifle wouldn't take the chance of there being any bullets in it. Why die here and now, if you can survive this encounter, get away and find new goodies?
Or you could tie down your victim, use them as fresh meat, if you got a vehicle (Car-like?) to transport them around in (Could also be used for plots, capture/kidnap a guy).
You would need to feed them every now and then and perhaps even give them medicine,
unless you just want to ensure them a slow and painful death of dehydration, starvation and illness. If ill they could also infect you, and their corpse as well.
I know, rather grim, but the wasteland is a dark and desperate place.
Sneak attack, if within 0-1 tiles of enemy, while hidden (+Hiding skill?) to gain a good bonus to-hit and damage.
I just like being a bit sneaky/assassin-like, especially in worlds like these. Cheap shots are the BEST shots!
Maybe even ranged sneak attacks, of some sorts?
Targeting limbs. For efficient/tactical take-downs, combat dept/realism, and the sadistic wastelander.
One could also swing wildly, if the dept isn't interesting, which it isn't for some people.
Think DwarfFortress (not that deep necessarily.), something along those lines would be really cool.
Friendly/Faction-based NPCs roaming around. Team up, trade or shoot them and take their stuff?
Potentially have some unique characters that gives out plots/missions.
Farmland tiles. I like the idea of establishing a base somewhere, and having a somewhat steady source of food is always great.
Of course one would have to defend against raiders and such. Maybe be able to change certain world tiles altogether, turn it into a fortified camp tile for yourself (And potential allies in the future?) or something of sorts.
Pistols/Small firearms. I read somewhere that pistols will be included at some point, but what I *really* hope for is this;
I encounter a looter, feeble and frail as always, with nothing but his hands. I decide to charge at him with my cleaver thinking:"..Easy kill...", but shit quickly hits the fan when he pulls out an old revolver and unloads a couple of rounds in my chest and arm.
I like surprises, even bad ones, in these type of games.
tl;dr: Hidden firearms, for surprise attacks in combat, or as a desperate last move for a bandit? (1)
Personally I'd like if I could use the Spy function to also get a little information regarding equipped gear on the target, like clothing, bags, etc.
The Eagle Eye skill would of course be needed, unless one had a scope or pair of binoculars.
Corpses. If fresh it could be butchered for meat (Mmmm, fresh meat!). An overview of injuries, like the player has in his Medical-tab.
Maybe even determine how long ago the individual was killed if one has the Medic skill. Rotting corpses in hexes could also infect you, if not properly burned or moved.
Camouflage clothing, and camouflage nets for camps to make them more hidden. Decreases detection chance.
Traps. A spike trap, either a hole in the ground with spikes at the bottom, or a stringed-up version waiting to smash your chest/face in. Grenade-tripwire traps maybe?
More animals and hunting. Maybe be able to deploy traps in hexes, and return to them later to check for trapped/dead animals/people/unknowns? Once one (if one can manage to) collects a fair deal of ammo, it could be fun to have the option to hunt deer or the like as well. Sometimes food on the table is worth more than bullets.
Scrap metals for primitive armor, vehicles, weapons, etc. Like welding-helmets, shields, plate armor torso (Maybe also a lighter version, which you're able to hide under a coat/hoodie?), gloves, boots. Could be used to reinforce cars, or repair them, or build them entirely from scratch with other components!
Pills/Plants that speeds up the blood loss recovery process, at the cost of higher food and water intake.
(1) Why should anyone waste their last precious bullet on a lightly armed or completely unarmed enemy, as the very first thing when combat starts?
Make enemies save it for when things go bad, or when the player refuses to coorperate (Bandit threatens player to back off/drop their loot, etc.), depending on the amount of bullets they've got, morale and such.
I'll toss some more in here, when/if I think of more.
Thoughts? I admit, I have not thought everything through.
