Bought it this morning, playing nearly all day.
One of the most interesting characters to show up so far is Newton "Stench" Akula. He shows up one day, wearing nothing but a shiv and an metal chestplate, complaining about his lack of pants. Lucky for him, the other colonists just killed off a bandit wearing only pants. Naturally, he's complaining about the quality of the pants, plus the fact that someone died wearing them. ...They were never cleaned, not even after... you know. And it turned out he was the brother of one of the starting colonists, Wren Akula.
Some time later, his latent pyromania gets ahold of him, and Stench begins to set fires around the main farm. I can't have this, so I have him arrested, and thrown in a tomb where I found some mercs in cryo, now converted into a cell. Unfortunately, the stone blocks where I built the cell door are blocking it from closing, so after a while, Stench waltzes on out. I sent the colonist, Sarai, to arrest him again... and he waltzes out again. And again. And again while I have Wren remove the blockage. Now Stench goes berserk, and starts beating the shit out of his captor. She's got a rifle, but wasn't ordered to fire(or can't because she's in melee), but he's got better combat skills and that metal plate(which may or may not protect from melee). They exchange blow for blow, seemingly evenly matched, but not good for Sarai. I draft Wren, but not wanting to go lethal, I hesitate to order him to attack his brother. Eventually, the need to protect Sarai(the main researcher) wins out, and Wren charges his brother with a plasteel knife, cutting off his thumb. Stench is subdued and thrown back into the cell while Sarai spends several days in bed from her injuries.
Over the next few days, the nudist teacher and one of the starters - an Empath named Tanya - as both have great social skills, try to re-recruit him back. Eventually they succeed. Stench has very high opinion of Tanya, although she hates him. In fact, both women in the colony generally dislike the Akula brothers, as both have tried hitting on them constantly.
Several days later, I figure out how to send a caravan out, and do so to the nearby friendly faction base to trade, with Stench and Tanya carrying some food and ancient drugs. Right after they leave, a caravan from the same faction arrives, and one of the escorts is Wren's lover - I really hope she doesn't mind him trying to sleep with other women. Shortly after that, and escape pod crashes, containing a very injured Yazuki "Gazelle" Hughes - Stench's ex-wife! Man, Stench is going to have surprise waiting for him if he survives the trip home.
