This is not an exceptional fort by any standards, but it is the one I've had most fun in and kept running for the longest time, currently I think 8 in-game years. I am not a very experienced player, I have only played for like couple a months (not counting when I tried to first learn the game few years ago), so I am very happy with Dungmaggots.
It has created wealth worth 4,5 million dwarfmoney, survived forgotten beasts, overland meagabeasts, sieges, and some annoying bugs like guests who never leave and outpost liaison who hangs around most of the year and never does diplomacy stuff anymore.
I currently have the liaison and many of the guests trapped in a tavern built over a volcano, with a 2x2 trapdoor in the middle of the room that I keep opening in hopes of fixing the aforementioned bugs. The outside of the tavern will be adorned with slabs memorializing these sacrifices.
I am also building more defenses in preparation for the next siege, as the last one killed half my military and I can't survive another one like that. I currently have a magma moat surrounding half of the fort and am making another one on the other side. I am also reviewing some of my solutions; during the second siege a troll broke the emergency exit gate to the lava moat, flooding the countryside with fire. Under that gate was drain tunnel for cistern, closed with a drawbridge, but that was not magma safe and it had destroyed. I later found that another troll had made it halfway the drain and would have totally annihilated my burrowed civilians, but someone or something had killed it before it got that far.
It is 28th Moonstone, 150. Guests are being sacrificed, another siege is being anticipated, but there is always time for side-projects. Suggest me things to do!
