I am on your side here! Why are you talking to me as if I'm against the idea?

If you read some of my posts in this thread you'll see that I am FOR the hammer bonus upon settling on a forested tile. I suggested 20 free

(instead of the 30

someone else mentioned) towards the first build in the city. This is the third time I've suggested it now. I don't see why you are asking me these questions.. But,
I play on 3.17 and Epic speed.
OK, thanks, that's all I needed to know. I thought maybe you were talking about Vanilla (yes, some people on this forum still play Vanilla) where you always got 30

from chopping on Normal speed, and you could have been suggesting reducing it to 20 when you found a city on top of it. I didn't think for one moment that you were against the idea.
So what you meant was reducing it from 30

to 20 on epic speed, for balance. How would this be balanced? For a start, if my (initial) idea was implemented, you would have to research Bronze Working before you can use this at all, so it won't help so much with the warrior/quechua rush since you can't build the city on a forest. But, more importantly, depending on which idea is used, you would have to either:
- Wait 3 turns (Normal) while the Settler chops the forest before the city is built,
- Get a worker to chop the forest as normal,
- Hold up production in the city while the forest is being cleared, or
- Get only a slight production boost per turn, over a longer period of time.
Actually, come to think of it, I'm not so sure about #3. If the number of turns for which production stops is constant, then it could be exploited somewhat in terms of an early rush in cities that would otherwise have low production. If that is what you meant, then you're right

. It would need to be changed somehow. Probably the simplest proposal, though, would be just to scrap this idea and make the player use a worker to chop the forest.
#4 would have similar complications (even if you're rushing, you'll get most, if not all of the hammer bonus by the time your army is built), and as such I'm not sure this is such a great idea after all. I've changed my mind on this one.
