Don't know what the chance of this getting read are, but could we please have the resources available in an embark site be mostly renewable?
I'm currently six or seven years into a new fortress. All the critters in my underground river, chasm and magma pipe are dead. Every river and lake has been fished out. The wildlife are all extinct, even the vermin seem to be extinct. Half the dwarf labours in the game are now useless because the resources they depend on are gone, the megabeasts died out in worldgen, and the only challenge I have left is infinite goblin attacks, which aren't especially worrying because it's just the same old thing over and over again; they never bring tougher units (trolls) with them, like they did in prior versions.
Things like rock and ore being naturally finite are fine, but in a game without a true end, the resources you're dealt with your site shouldn't be as restricted as they are. You shouldn't be able to fish out the entire damn ocean, chasms should repopulate, new sources of strife should swim down into your rivers, etc. We have endless goblin hordes to give us a challenge, why are the animals and monsters so limited? One fisherdwarf being able to fish out an entire region is ludicrous, and one hunter culling wildlife to the extent that they no longer migrate into the region equally so. I understand that there's more of a focus on simulation than game at the moment, but right now it feels like a sandbox world with very little sand in any given place.
(Can goblins be made more interesting again, too? I do wish they'd bring trolls and maybe other things with them again, and right now it's rare enough for them to even siege instead of just sending irritating ambushes and trivial babysnatchers; I don't care if they don't have direct access to the proper biomes, they're a civilised race and should be able to travel for their mounts/siege units.)
