E.g. in a farming games you can buy all farming upgrades and everything there is to buy quickly, and then there's no point to making money anymore, and there's no more goal to farming. I'm not the type who sticks around just to marry a bachelor, I'm usually way too bored long before that. To this day I've never actually married a single bachelor in these games because of that. Old HM games did provide some difficulty, but not enough, yet still I miss even those times when I had to manually push cattle into the barn, because it actually took time to farm back then! These days, I'm done with the farms in 1-2 hours, so days feel long and empty.
RF4S is the only modern farming game I know of that kept me interested for long, only because of its Hell mode for combat. Farming was still rather easy, but Hell mode made up for it by ensuring that I absolutely cannot finish the game quickly. Extra Options to raise monster levels by 100 helped out, as well. I'm looking for something like that: a difficult aspect of the game, not necessary combat, that will keep me playing. Maybe one day I'll even stick long enough with a game to marry

So I thought I'd ask if anyone can point out some farming game that is difficult?
P.S. Not a farming game will also do, I like a challenge in all genres, so if any idea pops into your head, don't keep silent just on the account of the genre.
