I have played about 150 turns with the Yor and here are some very early impressions from .60
1) Many tool-tip boxes are too small for their text with no scroll. This is a little thing, but becomes surprisingly annoying because it comes up so often.
2) Event videos for "First ____" were all very choppy.
3) Experienced noticeable lag when doing even simple tasks in the ship designer.
4) In govern planet window, the word "Manufacturing" overlaps the % text.
5) Showing food on Yor planets is very confusing. If there is any way to replace it with the Yor population cap for the planet it would be a great QoL improvement for them.
6) When attacking a fleet orbiting a planet, the defending fleet's stats do not display correctly in the battle preview window.
7) AI vastly undervalues tech when trading for credits. It is very easy to buy out all techs from other civs.
8) Mouse-over of other UP members bars tells you their % of votes, but this same information isn't available for yourself from within the UP window.
9) AI still a long way off, but starting to do smart things like defending planets, starbases, and shipyards.
10) Yor ships are the best looking yet. If things keep going this way, the Iridium and possibly the Alterians may need a second pass on their ships to keep them up to snuff with the other civs.
11) The Yor are super fun. Their growth mechanic synergizes very well with the new approval mechanic. They take a bit more macro, but I found it fun to keep fiddling around to optimize growth vs. production.
12) Hard to say yet, but I think Yor might be a little OP right now. Their ability to grow small planets very quickly makes them a powerhouse toward the end of planet rush.
13) The Yor only need to devote the smallest amount of manufacturing to Assembly to grow at .2/turn. This means they can make good money or put out tons of research while growing.
14) New approval is simpler, but also more sterile. The old system was confusing and needed tweaking, but the fact that it was much more difficult to game meant it felt less like managing a spreadsheet than the current version.
I've just scratched the surface of the new build, but it is clearly a nice step forward. The game feels much more like a complete game in this iteration, and it looks and sounds great. The Yor are tons of fun to play and add a lot of character to the game. I really hope they are encouraged to do something this distinct with at least one of the final two races. It is amazing how much distinct factions can do to add life to 4X.
