Hey everyone !
I would like to share a few thoughts about farming and a way to not make it rely on RNG.
Plant growth would have three stages, growing, mature and withered. The mature stage gives fruits but no seed and withered gives seeds but no fruit.
Plant would need 3 days to grow and three more days to wither.
Without LoTL, plants bear three fruit or two seeds.
Lvl 1 : +1 fruit
Lvl 2 : +1 seed
Lvl 3 : +1 fruit +bonus chance to fruits seeds in loot
Lvl 4 : +1 seed +bonus chance to find seeds in loot
Lvl 5 : +1 fruit and withered plants are resowed automatically
At lvl 0 you would have to let 2/3 of your crop wither to fall back on your feet,
at lvl 2 1/2,
at lvl 4 2/5
and at lvl 5 1/3
You could ensure that your farm is self sufficient by managing it well and LoLT would make it easier to manage.
I think it would be also easier to tweak to achieve good balance in this form.
About the tedium, you would still have to replant but the extended growing time would alleviate it.
