Can anyone update this with any info on new wonders that aren't discussed here?
Let me see if I can go through the wonders with my own opinions:
Crystal Lighthouse....I don't find much use for this. I have all the goods I need, but newer players might want it. I use this to build it and then destroy it so I can rebuild it again and get some broken shards I use for other things.
Martial Monastery....Indispensable if you do any battling. Without it you don't have much chance of winning most battles.
Tome of Secrets....mostly worthless. A few supplies when you scout a province? A kp here and there? Not worth building.
Golden Abyss....it is ok I guess. The coins it gives aren't that important as you go on, but it is nice to have the population. Because it is so small and it takes a lot of kp to level it up, it gives you one of the best points per square ranking wise if you get it to a level 15. For that reason, it could be worth something to me, but I have other things I want to build first.
Endless Excavation....the relics are useless. If you do any tournaments at all, you get plenty. Getting some supplies every 24 hours....ok, that is fine, but you need so many supplies. It will be one of the last I ever build.
Watchtower....I don't know much about this one.
Thrones of the High Men...I'm drooling over the thought of getting this one. Maybe one day. I really want the ranking points.
Dwarven Bulwark....upgrading the barracks training size is useless to me. I already have enough troops sitting in the queue. I don't need more. Producing some swords every 3 hours is ok....I can use them as bait in the battles. They die and protect my more important troops.
Mountain Halls...It really boosts your goods production and this is handy. It also gives you population and I always need population. I think this one is quite useful.
Prosperity Towers....the boost it gives the power of provision spell is useless to me since I don't use that spell, but the supplies it gives are very needed. They keep draining us of supplies with no way to get more. Any way to get supplies are needed. I think this one is quite useful.
Blooming Trader Guild....anything that shortens the time to slog through the guest races is useful. I wish I had had a chance to get one before I hit the orc chapter. Plus, I like the bumblebee.
The new orc wonders I know nothing about.
But read this whole thread. BobbiPiazza has a great post about when to build wonders at all. Please keep in mind that these are my opinions about the wonders. Everyone has a different city and so you might want something that I don't.
