First off, let me say that I'm enjoying this immensely and haven't had any of the game wrecking bugs that MoM had. Nothing sucked quite as much as investing hours into a MoM session and then seeing one of your galleys with practically every power imaginable and knowing that your game was irreversibly corrupted.
Now then, on with the quibbling.
1) The nation of Umber keeps contacting me to let me know they would like a marriage. Going to negotiate one with them they respond with 'Of course not, why would I ever force one of my family into marriage with YOUR family?'. I can't offer up gold or diplomatic capital to adjust things, and the balance says 0/0. He only has a daughter, I have two sons now. Either I'm missing something as far as making the offer sweeter for him, or he's contacting me to pester about marriage when he has no intention of accepting one with either of my boys. AI issue or ignorance on my part here.
2) The game does a poor job telling me which technologies will raise my Quest or Notable location levels. I've been trying to guess which offering will do it at each increase, but not doing a good job of that. Was one period where I had to receive three advances before hitting the one that boosted me up, and this was with reading the text of the techs and trying to choose the one that sounded most likely to let me do what I was trying to do. Eventually I will know exactly what does what, documentation or not, but less trial and error is still nicer.
3) There is a display bug related to city names. Not sure what triggers it, but I've had as many as four cities with the same displayed name. Cloth map will look correct, but graphical map will be filled with multiple identical city names. The mouse tooltips will show the correct names.
4) There was a discussion earlier about how bonuses multiply. What I took away from that was that a 10%, 20%, and 50% bonus would be 1.1*1.2*1.5 = 1.98 = 198%. Looking at say food production, those would just be summed to 80% bonus. Are there places where percentage increases compound on each other, contrary to behavior in cities? I haven't noticed any yet.
5) Edit here for one more thing. I've noticed that some buildings seem to function like Wonders from the civilization series. But there is nothing in the text of these buildings to indicate that they are unique and special. They simply disappear from the other cities build lists once you queue one. Just like number 2, more information would really be better.
Nothing else really jumping out at me as far as oddities so far. Once again, excellent work gentlemen. I have every intention of staying up all night long and it has been quite awhile since a game made me do that.
