Yeah but something to consider is that you can't have nearly as much planted in AWL as you could in the games where the sprites could help you. Still, it'd be nice for them to be able to help you - as it is, they're pretty useless...
You don't really need the harvest sprites. Taking care of animals is easy, just milk, talk, brush, hug, feed, wash, and clip them. For crops, you just have to water and harvest. Not that hard. For me, all of that only takes 1½ hours out of my whole AWL day. And you wouldn't want to know how long that is (its longer than 20 hours)
Yeah it might not be that hard but it's pretty repetitive, as you have to milk cows more than once, water crops more than once, etc. It would definitely be nice to have the sprites cutting down on some of that work.
If your child becomes a farmer will he help you on your farm?
