I have played and finished about 5 games since I got VV a few weeks ago. Like a lot of ppl, I've realized that anyone can heal, even the kids. So why have a doctor? I've just run a speed game (ya know messing with the pc clock to finish asap ...3hrs 15mins.) and I didn't bother with giving anyone healing. Still finished the game with no problems. So again I ask... if anyone can heal why do we need doctors?

When you leave the game running unattended and anyone gets sick, only a checked doctor will go to them without you physically taking someone to heal them. Also, sometines you don't realise someone IS sick, especially if you have a high population, but a doctor will "hear" the sick person even if you don't

Why have them after GC?

well I suppose you could untrain them :P j/k. Don't villagers still get sick after the GC? I've never seen the GC actually go to a villager on his own to cure that villager

yes they still get sick and no he's to busy having partys.

Sorry.. was thinking of trainee/low adept level... you're right.. I have seen a master or near master doctor go. Never seen a youngster though! Not sure I'd risk figuring on that happening if I were going to be away for quite a while

There is really no point in anything but Doctors and Parents after the GC has been at work for a while - he has supplied all the food (no need for Farmers) and there is nothing left to buy (no need for Scientists) and nothing left to build - except possibly repair the hut.

Just like real life...everyone needs a purpose. The people farming and fishing look happy, builders like their trade etc. Everyone needs to be trained and kept busy. Don't want the little dudes to get bored!!
