I doubt that it will be a Nx feature.
It's kind of troublesome to wait for the farm ores to regenerate...
Takes a few game hours to regen I think.
In other words, this is just a side thing you do in between dungeon runs or something.
(I think we overestimated this system but my farm is rather young so I need to wait and see whatever happens.)
It costs money to buy the seeds and bricks so it's not a standalone system in the sense that you can just choose to play farmville in Mabinogi and not go far into other aspects. Your money has to come from somewhere.
The farm features are all under the A button (FArm), from anywhere you are. E.g. Your character can be in Uldah but your farm is in Physis. It's an auto-warp to an instanced area as mentioned.
Also, seems that you merely have to wait for a timer to fill up to build something or to grow a crop.
Chick =/= young chickens, it's farm exp for farm levels. I wonder why they call them chick, it's kind of weird to me.
The ores from the starting ore patch are farm currency for farm actions.
