Units are just people. Workers, soldiers, etc... Probably, that would include things like hunters and forragers in a survival setting. As for resources, it would make sense, but some games do limited and some just go by as long as the infrastructure is there. In a survival experience, I imagine it would be a mix of the two. Out in the world, there would be limited supplies, but you could create farms and the like to get some regularly occuring resources. One thing that a lot of games have been doing (popularized by Minecraft) is the infinite world, where there's endless resources, but they can be exhausted in a given area, forcing you to roam. That could be an interesting dynamic as well.
