Commerce kinda needs a role to fill as a later game tree. Either just make it generally solid or make it all out goldfocused.
Rationalism needs a nerf aswell as something that ties it in with the scientific victorycondition rather than just giving you a ton of science(which is too good)
Aesthetics got some policies that need work but in general i think that's the best balanced tree at the moment(Well it also needs a powerbump to actually make it better than the openertrees).
What would 15% GA points mean? 15% toward current Golden Age?
If it needs to be there I'd rather see it be a flat value your golden age progressionspeed does not really increase that much as the eras progress (atleast not with the current build, in fact the scaling unhappiness actually makes it harder to get GAP later on), which would mean a scaling bonus would keep getting better as the game progress (which isn't what we were trying to do with the openertrees afaik). Just bump the number up to maybe 100 or 75 and it's fine(guess it needs to scale with gamespeed aswell).
2) Agreed, but better workers is still pretty good on its own
I honestly don't really see the need for that policy, tradeunits have nothing to do with liberty (imo) setlers and workers do (But if you want it TvWneutral they kinda don't)
3) Agreed, but they also have a little more wide bias (and could fit in commerce just fine).
I think cheaper roads works fine in liberty, more gold for cityconnections however, not really. Not sure it makes sense in commerce either however, maybe from the east-india-company like in cep?
4) I think we can just do scaling instead and it would be a useful effect.
The science should probably scale with your scienceoutput (anything else doesn't make sense) but as mentioned before I don't think the GAP should.
5) I'm not sure about that entire policy really, it seems somewhat wide-biased for one, but it isn't a bad effect to give flexibility and +1 culture for amphitheaters does help the tree a bit on culture without altering the X culture per building/tech formula yet.
I would rather just see a flat 2 production or 1 food 2 production or 1 food 1 production in all cities instead. Small bonuses to everything is kinda meh. (maybe one production +1 extra for extra productionbuilding?)
@Stalker, doesn't Honor also get culture from city conquests in the current design plan? Not sure why the camps would be necessary on top of that, but okay.
I agree with stalker about the camps, you should be encouraged to clear them out instead of just farming them with archers.
