Glacier is pretty good. The trouble comes not from aquifers or lack of water, but from lack of soil. Glacier lack soil of any kind unless you embark with a bit of actual land as part of the embark area. The last glacial embark I did, I dug out a large room and flooded it. Water does evaporate underground regardless of temp. I drained off the water, let the puddles evaporate, and planted in the resulting mud. I'm actually good with anything too in terms of mods. Kobold kamp, DAII, or vanilla. I know wilson said he was interested, so lets get his input.
heres what DAII does
It's topic is almost always at the top of the "mod releases" section of the modding forum. Personally, I think it's a great mod for dwarf mode. In adventure mode though, it is severely outclassed by wanderers/adventurecraft.
I'm a bit leaning towards Kobold Kamp actually. Never done that before.
