- upgrades for tools for a faster farming:
1. maybe while using to generate experience or
2. with ores or food that gives boost for working
3. increasing skills for playtime, like more time until the character needs water or food or the tools become better
- plants and flowers that can be put in the press to make colors for clothes
maybe put in the press fruits etc to make juices (maybe wich can be used to generate the top minded boost-effects)
- tameing and (maybe breeding) for animals (so you have to tame a male on too)
1. cattle gives milk and you are able to make cheese, yogurt, butter and it gives (meat and leather (thats in game))
2. poultry for eggs, meat and the feathers for arrows and maybe pillows
- for single and maybe multiplayer: the possibility to uses npcs for working in your quarry or on the fields maybe for fullfilling a quest or for payment in resources
and last but not least maybe some exotic fruits: coconuts and pineapples would be great
i know thats a lot but i think its all about the crafting and skillsystem and so it would make sense.
I hope you like the ideas
