Finaly I was playing around a bit, now I want to share a few comments about v1.5. They are not sorted, this is just what came in my mind.
- I love the new ressources thing. IMHO they improve the game pretty much.
- Ressource Icons (copper, tin, granite) are not shown like suggested on map. (Im afraid, this is Firaxis' fault, since in Civiliopedia everything is shown right, just on (premade) map the icons of iron, aluminium and coal are shown instead.)
- there is an empty "TEXT_KEY_RESSOURCE_COPPER.." entry in Worldbuilder and Civpedia
- You added some resource bonusses to a row of buildings. Maybe you could change some again so that they work like circusses: you need the ressources to build them? The shrine of the sea seems to be a candidate for this.
- Some more restrictions would be nice too, I felt. (for example one need building A to build B as well)
- I like the changes you did, new economic balance (less gold) worked pretty well to me
- Some wonders are very powerfull (to powerfull in my personal opinion). But this is a matter of personal taste, I think.
- Do you plan to rename Wonders/buildings? Or adding new ones? So... do you need suggestions here? (I just felt some buildings and wonders are "wrong" in bronce age - its basicly cosmetics, but if adding new ones it's gameplay as well)
- cultural victory is not working yet, guess this has to do with capped techtree. (I was trying to win this way on Diff 6 with India, but I finally lost interest, becouse everyone was on same tech level, and I was researching same tech again and again.)
- I like the "Art of ... tech" idea, but ...
- I felt, the "Art of ..." techs comes to late. They are on the end of the tree, so... normaly they don't have much effect on the game anymore. After a while everyone has every technology. Even on Marathon they had.
- time scale is not working yet (im still in the year 1600 AD after 500 turns on marathon (or so) - I just love to play marathon, maybe this is not suggested here, but... I just love it. xD
