Started a pocket world with no history and a minimum of civs for the fastest world creation I could get. I put beasts and sites at max, but I still ended up with very few megabeasts. And no humans at all.
So I said "Heck with it!", went into adventure mode instead of dwarf mode, took my demigod axedwarf, and went on a quest to kill everything.
I started out in a labyrinthine mountain hall, where for quite a while the only other person I encountered was a small child, who greeted me and immediately told me to go kill a night creature as soon as I returned his greeting.
I then wandered around, found beds and bedrooms, and eventually found a bunch of dwarves conversing. I yelled out to everyone, and that seems to have permanently disabled my character from speaking to single entities (except his deity) after that. He just yells. All the time. I got a speardwarf to join me, though.
Eventually, I found my way out of the mountain hall via a long spiralling passage upwards, only to discover a trade depot with a bajillion dwarves in it, all of whom had several pages of dialogue for me to slog through every step I took. I fled, left the mountain hall, and went to the nearby hill dwarf town. It was fairly empty, seeing as how there were something like 95 notable creatures in the world, but I found a meeting hillock, talked to the sheriff, and left to go do something violent.
I then decided my first kill should be the world's only dragon. Other than a wolverine fleeing at my approach(!) the trek was uneventful. I hunted that sucker down, walked up behind it while it completely ignored me, and hacked at its head and neck with my battle axe for five minutes, until the speardwarf overcame his terror, came up, and stole my kill with a single blow to the unconscious beast.
Grumbling, I then decided to take out one of the world's only two titans. Running up into the mountains, I wandered for quite a while, until I was distracted by a conversation. Thinking it was Rakust the kill-stealing speardwarf imparting more tales of things we could go kill (as he was wont to do without any prompting on my part) I checked my recent events, and discovered it was a wolverine man, telling one of his two girlfriends all about how he assaulted me just seconds ago. I had absolutely no recent even text suggesting such, so I decided to teach the punk kid a lesson about idle boasting and killed his girlfriend in front of him. She was in shock, screaming that this couldn't be happening. I felt guilty about it, but figured I should probably put her out of her misery. Then I killed him, which went much more easily because he was actually hostile, apparently unlike the dragon. (Up until that point, I was guessing the "Really attack this creature?" thing was a bug, because how could dragons be nonhostile?) That made me feel guiltier about killing the innocent wolverine woman, as I realized only one of the band was actually hostile. Then I chased after the other wolverine woman, ("No witnesses!") but she ran off into the distance faster than I could keep up, and I wasn't much of a marksman. As I left the area, I heard her voice echoing from the distance talking to someone about how she just assaulted me, but I couldn't find the source and left frustrated.
The titan-slaying quest continued, with me assaulting a group of peaceful kea in retaliation for all the theft their kind committed in dwarven history. I decided to go into sneak mode to keep from alerting further wildlife, allowing me to kill more keas without them escaping. As I butchered the corpses, I discovered that I had the option to pick a nearby flower, so I did.
Eventually I reached the titan's shrine, but it was heavily forested, and trees had removed many of the ramps I'd come to expect from mountaineering in previous versions. This made the place surprisingly mazelike. The titan was tricky to find, as the shrine was sloped, and trees were everywhere. But eventually it found me when I was looking for the source of the strange colors I was observing. It turned out to be the titan's line of sight indicator I had been investigating! A savage battle ensued, with me and the titanic hairy insect clashing on the steep hillside, any dodge potentially fatal. Luckily, I eventually fractured its legs enough to slow it down, and hacked off its head after a few neck strikes failed to work.
Then the two of us traveled a ways farther in search of a night creature lair. The closest lair was a ways southwest, so I ran down the mountain, assaulting random wildlife for axe practice as I went. I killed a moose, then a few ravens, then some turkeys I found scratching for grubs in the branches of a sand pear tree. Somewhere during this time, I lost my speardwarf companion. Now I'm a bit worried about bogeymen...
Finally I found the lair. Inside was not a night creature like I had supposed, but a named dingo. I snuck up on it and chopped off its neck. Not its head, mind you, just the neck. The head was still attached to its body... somehow.
Leaving the den, I discovered to my delight that I had left the mountains for the first time since I left the hill dwarf settlement, and could fast travel! There's a nearby elf settlement! I figured I'd go over there and see if I could recruit an elf to repel bogeymen. I take one step on the map screen and...
Ambush! A black bear decided to attack me. That was all right, because I decided to attack it as well. So I charged towards it, intent on removing its head. The bear, on the other hand, was apparently Australian, because it immediately climbed a tree and attacked me from above, dropping on me when I tried to hack at it in return. Luckily, I managed to roll away from the drop bear's subsequent attacks and was able to stand up again in time to lop its head off.
With no further interruptions, I headed into the elf retreat. Searching around, I discovered the existence of tree houses on the overland map, but I'm having some difficulty locating them in the personal view.
And that, so far, is my first adventure mode foray in DF2014. Strange monster conversations, labyrinthine mountain halls, severed necks, flower-picking, drop bears, and tree houses, all within the span of a half hour or so. I'm impressed!
