Fairy Blooming Wonder:
25% wholesaler offer improvement
This won't be of any use to a very advanced player? By the time you get here, you should have cleared hundreds of provinces and you should have a very advanced fellowship. When you have to clear provinces it takes tens of thousands of goods to do so per sector in one province. You need 250,000 goods to get through the whole province. You certainly aren't going to be buying those goods 500 at a time. I don't care if they remove the cost of the wholesaler completely, it doesn't matter. The only time an advanced player (someone who has progressed far enough to have researched this tech) buys goods from the wholesaler is when they have extra coins or supplies to toss away.
40% reduced trade fee
Once again, in order to be an advanced player, you have to have a very good trading system in place. You have likely been playing this game for 6 months to a year by now. With the new province requirements, you couldn't even get to this level if you wanted to without having at more than 180 neighbors. Also, you will have had to make trades in the thousands of goods regularly. Yes, if the game is totally broken and you don't have a fellowship and you are stuck in a desert wasteland of zero neighbors, then this may be of some use to you....but only if you got super lucky and that one person you needed to trade with was just outside your neighborhood. Most worlds have trading posts where you can go to make the large trades you need if you absolutely have to, so this is totally superfluous no matter how reduced the trader fee is.
5% Portal production boost
The portal production for all races gets boosted. Ok...yeah....that is nice. But it doesn't work on the dwarven portal because you are past the dwarves by the time you research this. It doesn't work on the fairies for the same reason. It will work on the next race and that might be of some use. However, in order to build this wonder you will need to research tons of provinces, and give away tons of KP trying to get these runes (you will have a one in 6 chance). By the time you have built this wonder, you will likely be through the end of all future races. But if not, and the game stalls again for months and months it is somewhere to stick that KP.
But don't forget what you forgo when you build a wonder....you lose a lot of space and you lose boosted relics. That will cost you goods every production for the end of time. Is it worth the cost for maybe that production boost if you build it before the new races are here? That will be for you to decide. I know it takes a long to slog through the new races tech, but what do you get if you rush through it? You get less game to play. You get to wait for months and months for something new. It isn't so bad getting through the tech more slowly.
AS WITH ALL WONDERS, ONCE BUILT, YOU WILL NEVER EVER EVER GET BACK THOSE BOOSTED RELICS. So decide well before you choose. Even if you delete it, your production level is lowered for all time.
(All percentages of boosts are for a level 1 wonder and will go up as you upgrade your wonder, but no matter what the percentages are, the principles above remain the same.)
Sorry...this got long too. One more post and then I am done!
