Running thought on this...
For the most part, I like the changes you have put in place and are working on for the closed BETA. Yet, I seriously feel the game is progressing in the wrong direction, towards a higher class of internet gamers with big wallets and little hearts. For a long time, InnoGames has presented games for the common person- games you could log into once a day and still have fun, or log on every other hour and enjoy it. At this time, I am almost even thinking about leaving the game, it has become so unfriendly to play... there is great stagnation once you reach the middle of the game due to the exponential rise in prices yet rather linear yet jerky rise in production of gold and supplies, and the lack of rise in production!
I seriously think goods production is too low regardless of what... consider having EVERY province having a resource, and some having extra treasure or such... gaining a resource is something I want a heck of a lot more than anything less than 10,000 gold and 10,000 supplies, because that's how much one could spend trying to get some production over as long as two weeks just to get past a tech... the market is completely stagnant at this time, so that's not helping. Perhaps you should consider allowing trading outside of each neighborhood on the server level. Either that or go so far as get rid of a few resources and replace them with others... or else players in the middle will spend days trying to get resources for things.
Another idea would be to have certain technologies give a 50% or 25% increase to the production of [certain] goods workshops... for instance, handicraft might increase Marble production, Agriculture might increase Wine and Dye production, and Iron Works might increase Stone and Wood production (from the new tools made with iron). These logical advances can give a better production of resources, and should probably be placed in the next age or later on in that age. One could even have technologies devoted strictly to this sort of raise, where there once were expansion technologies.
Right now, the game is fast in the beginning, medium in the later end (at least for those with diamonds or lots of activity), but very very slow in the middle when you don't have the provinces or perhaps not as much time as others. If you want the game to be fun, you need to make things more accessible for those of us who are the run-of-the-mill player, not the super-player who has $100 in a paypal he's willing to spend on the game.
speaking of money... I see nothing has been done on the price of diamonds, regardless of the discussion I hosted and the near unanimous and widespread agreement that the price was too high. I sincerely hope the team will consider reducing the price considerably soon... as soon as it hits a more acceptable value, I will consider spending money on diamonds... until then, those buildings will remain unbuilt. These changes for diamonds ask for astronomical prices for menial things... I now wish greatly that such a system loosely based on the tribalwars premium system could be put in place, where, for instance, for one month, all resources would be auto-gathered at the end of production, units who die would return at 1 HP and would be healed faster... a system of
expedients, not just bonuses... of course, I understand the paid buildings, and I think those are great (the most useful thing to do with diamonds at this point), but click a button and for $20 have your buildings collected? That's a bit extravagant...
Lastly, I feel that population was poorly balanced from the start... houses offer too little for the massive population required by buildings... at this time, my poor little city can only offer area for two production buildings and three military buildings (probably more due to my failure at proper city planning more than anything). The "balancing" changes have only made things worse, in my opinion... please consider restoring much of the population held in houses and increasing the happiness production of large structures, especially churches (to compare that church and it's price/happiness ratio to public baths is very painful... I'd rather loose those 7 tiles to the baths than loose all that money and supplies to the church).
