Simply put - I'm enjoying the game a lot! I love playing on large maps (waiting for Huge for 64bit) - my Kingdom stretches far, it evolves, questing, warfare, research, spells - everything seems great. Love the variety of spells and Books so far. Marriage and your kids- wow these guys get a lot of essence - leaves my original sovereign looking like an amateur. Different monsters enrich the world, but sometimes I find that there are a lot of monsters out there, which is good sometimes, but sometimes it gets frustrating as those thing slay waste to resources and caravans.
However I was and still am confused about the tech tree - I really don't know what to research on some bigger trees like Civilization, warfare - I still can't find the tech to upgrade your houses, get some normal roads - not the dirt ones. Also It is a bit annoying when resource buildings, that take 4 spots are included into the city and they take up building tiles - often when I research for new resources to appear, they pop up right next to my city and building them include them into the city.
Some bugs- Air Shard temple simply does not exist. I get the shards, it shows as building a temple and at the end it reverts to basic visual of the non-built shard. If I build my city around an Air shard and build the temple to harvest it it shows as just black tiles - nothing is there.
Also I sometimes shards appear on top of other world resources - I had an Earth shard appear on top of a gold mine - it showed the visual of both, while on cloth map it showed the shard - the mine was there from start of the game. Obviously I could not build a temple there.
AI - some Kingdoms don't expand - they build their city and thats it, while other Empires and Kingdoms expand.
Overall I'm loving every moment so far!
