I think I'll have to pull out an oldie here - a game called Worlds of Ultima: The Savage Empire. from good ole Origin.
I was very impressed by the masses of options one had availble to the player, and when considering it is somewhat old being from 1990

The options one had for interaction with the gameworld has me still drooling to this day. For instance one could remove flax from plants, and weave it into cloth. Then it could be cut to shreads with a knife. These cloth strips could then be used for bandages or be dripped in a tar pit and wrapped around a branch (which you naturally got from trees) which made a torch, or you could use them as fuses for home made bombs.
These bombs where made by you collecting clay, then taking clay to a furnace you could make pots. Then you needed to collect sulphur from sulphur pools and burn branches for charcoal, collect nitrate and then combined it all in a mortar and preston: gunpowder - and then you could make bombs. I remember one big dinosaure you had to kill it by exploding bombs near a big rock and move the rock out over the cliff.
You could also find a fire extingisher at one point, and while it lasted you could use it to cool lava so you could walk across the lava streams.
You could collect food from various plants and fish for it. Or you could kill animals and collect meat from them.

And much much much more.

Danged I miss games of this scale and level of interaction ... it almost makes me sad when I think of the games out today and compare it to such games as this. Especially when this is 14 years ago.
