I am just wondering if anyone has explored both factions yet? Is there one you prefer and why?

Yes. Nature, for the simple fact that it's *much* easier (in my experience at least) to keep food around once you have the first level of Nature. Just my opinion.

Means u find more Food in nature Faction?

I guess so, I just choose nature and already more food is available

Nature replenishes food sources more often, as clearly stated in the "?" on the Nature Faction.

Yeah, I like Nature better. I wasn't so interested in magic.
