This sounds really fun!I've always thought it would be cool to play a sandbox game ala The Borrowers or The Secret World of Arriety where you play in a normal world (like a family house and surrounding neighborhood) but on a tiny scale.
The normal survival game features could easily apply:
I think I've even seen a few people try to make a game like this but I don't know of any that got completed.
- Go out and scavenge for food that gets dropped on the floor, or raid the cupboards and tear your way into a cereal box.
- Build a home base inside the walls or up in a tree.
- Avoid dangers like being seen by humans, or the family cat, or birds of prey.
- Fight bugs or rats or other small pests with makeshift weapons you find, like a toothpick or a needle.
Not to be "that" guy but I'm pretty sure, having "needs" was originally baked into the whole Radiant A.I anyway. I seem to remember Bethesda making a pretty big deal of it during their development videos for Oblivion. That the npcs in all the different villages and cities all had own routines, that included eating and sleeping as required and evening doing chores and visiting family in other towns. It was at the time, very impressive. Taking that and dialing it up to 11 would indeed be something to behold. I'd love developers to build on the how the world and npcs reacts and changes to the players actions, in more interesting and believable ways. Especially in its crime and law enforcement mechanics. Neither modern or medieval openworlds have really nailed a believable law enforcement system yet in my opinion. I do think some games have implemented it better than others though.Yes, exactly that.
Edit to add: But also with Sims-like "needs." So if you're sleepy or hungry, your performance suffers. As does the performance of NPC's.
