I mean, fire is the basis for most civilization
Dorfs do not have fire, too. At least not explicitly (one could assume kitchen have fire).
Technically, you are correct. However, it must be
assumed that many workshops - including the Ashery, Kitchen, Still, Kiln, Smelter, Soap maker's workshop, and all types of Forges and Furnaces - use either
fire or
magma for heat. To do otherwise would require magic.
Then again, DF is a fantasy game.
Exactly. And in this setting, aquatic rare are not unhearded for, if rare.
In a fantasy setting like DF, perhaps. Fantasy tends to take a lot of liberties with logic and science. But I've read various hard science fiction stories which argues that the
evolution of a sentient aquatic civilization is nearly impossible without being naturally amphibious - citing the lack of fire and the subsequent difficulty in development of tools beyond stone age level (rock, bone, and shell) as the primary reasons. And if they're an amphibious pre-industrial society, it seems only logical to have their primary cities on land for all the benefits it presents.
Anyway, I'd consider it a terribly unfair (and boring) advantage if most enemies could not attack my fortress simply for being underwater.
I think this kind of civs would have appropriate enemies to attack or siege them. Yes, it would need to add many things (like generating interesting ocean bottom). And FPS. Oh Armok, FPS. You would have race that in practice fly (because entire embark tile is submerged in water, or at least significant lower part in case of shallow sea close to land). It would also change way to show tiles being underwater. And zilion other things.
Yes. It sounds like Toady One would have to go out of his way in order to make the seas in DF playable for aquatic races - a lot of stuff
above and beyond allowing building on the ocean floor and patch issues. Would there be a guarantee of enough large ocean critters for hunting to provide
all food requirements, regardless of being randomly generated? If not, how would a playable aquatic race
farm? Wouldn't that require the addition of a lot of edible aquatic plants? Yes, it would be a lot of work. And probably requires fixing many bugs and serious FPS issues before it could be seriously considered.
Erm, one thing at a time could be good strategy. So add cuttlefish and other deep sea animals and monsters, even if you almost never see them, even on ocean-side forts.
...this is only an issue atm because we have very little interaction with the oceans.
I agree. But the addition of a lot of dangerous deep sea animals would be more
Fun and useful to dorf players if only dorfs could put out to sea in boats and ships. (I'm pining for
pirates and viking-style warships...
And ship "caravans".)
