I have started alone.
It doesn't sound super-hard, but I sounds fun to me. Possibly "Fun".
Here's the Challenge Rules:
Location:
whereever, but prefferably somewhere with little/no fresh water
Embark:
7 peasants
1 pick
1 pig tail
0-1 cat (zero or one. NOT 2 or more)
0-1 dog (see above)
Additional:
The ONLY PLANT YOU CAN GROW IS PIG TAILS. (This is the core of the challenge, imo.)
You can buy whatever you want from the traders, but all seeds other than pig tail seeds MUST BE COOKED ASAP.
Cooking booze is allowed, but is looked upon like this: > : (. (EDIT: actually this is the only way to get something eatable from pig tails, oops)
(Optional) After a year or two (once you have a cloth industry running), you can plant and mill Dimple Cups for dye.
(Optional) Low population cap, ~20. I just like low pop. forts. Easier to manage imo.
I haven't tried it myself yet, but I do plan to sometime this next week. I duno if it's been done, but I've never heard of it before.
I was thinking it could be a succession or community fort. Or perhaps several players start at the same time (optionally in the same world/embark area) and we all chronicle our successes/failures.
Thoughts? Opinion of the challenge? Ideas for an in-universe reason 7 dwarven peasants are stuck in the middle of nowhere with only a pick and a single seed? Also help decide if we should do it succession, community, multi-chronicle, or something else.
I intend to try it and post about my success/Fun one way or the other.
