Yes, I posted elsewhere the other day about how we really should lengthen the growth time of Wheat to something like a week IRL. Although, I also would like to see volume increased, storage made easier, and harvesting/grinding flour made less clicky. Basically, I think farming should be a role that caters to people who _arent_ around very much, who like a slow pace. Log on now and then, do a few little tasks, log off. Thats certainly not a favouring of realism over fun, because not many IRL farmers could afford to behave like that!
Any kind of 'window' for harvesting would suck, except a very long term 'seasonal' window.
