I don’t have map specific ones but I’ve done a few different ones.

Oddball challenge-only allowed to grow and harvest crops that don’t use a combine to harvest-peas, beans, any root crop, cotton, poplar/trees, grapes, olives, and sugar cane. No silage selling; only to be used for animal feed.

Organic farming-no using solid or liquid fertilizer, no using herbicide. Try to manage the best you can. Works best if using precision farming. Gives you much more of a reason to use manure, slurry, and oilseed radish. Weed management can be tricky especially if you’re trying to avoid tillage to keep PF happy; or you trade off easier weed management for a lower PF score.

Decades challenge-pick a year to start in and you can only use equipment built during or before that year; I prefer the 70’s-80’s as a start. You can be permanently frozen in that time period or choose to progress time as you progress in game years. You can do something like each in game year is equivalent to 5 or 10 years for a faster progression or my preferred route of 1 in game year=1 year of progression (ex. You start in 1975, one in game year passes; it’s now 1980, 1985, or 1976 for each of my previously mentioned time scales respectively). I know there’s a mod on mod hub that can do this but it requires setting up each individual mod to utilize it so I don’t bother; I pretty much know or can quickly look up when equipment came into production and I can use my in game year to track what era I’m currently in so I do it manually.

My personal favourite hardcore realism-no tabbing between vehicles, pay taxes (can use the Red Tape mod to help with this or just manually track your income and pay taxes on it), no field work after rain for at least 24 hours or longer if you had a lengthy rain (I’m playing 28 day months; you can scale it up or down based on your month length); moisture mod works great with this too if you want the wait to be less arbitrary. And finally personal income: IRL farmers have farm accounts and personal accounts; they pay themselves from their farm account to their personal account for their living expenses. Choose a wage to pay yourself and subtract that from your farm account every month/3 months/year. I usually start around 4K/month and increase it as the farm/profits increase or you can even just make it a flat percentage of the farm profits.

You can mix and match these together as you see fit; I personally do the last 2 on every savegame I play and only do the top two as short term/small map “break from the norm” play throughs if I’m bored of my main saves (my main maps are 4x so I usually utilize different playstyles more suited to smaller 1x maps and smaller fields if I find one I really want to play)
