I had quite a large civilization, had all cards in Homeworld unlocked, was well underway in Weyworld.

Funny thing happened after the update:
The cards for settlements and villages are no longer separate - it's 1 card/power, with varying degrees of effect depending on whether you upgrade it using gems (10, 20, 40 gems).

It kinda feels like I spent all these stickers unlocking villages (bigger settlements), but now I have to re-buy them using gems (thankfully the gems can be obtained easily by sacrificing some followers - but still, it feels like "paying" for something I already had).

Same for the layers of sculpting. I had unlocked up to the highest level in Weyworld using stickers, now I had to spend 10+20+40 = 70 gems to get my 12 layered sculpting back.

The other upgradable effects on powers I don't mind paying for so much.
More effective shrines? Sign me up.
Bigger meteor splash? Why not?

As this isn't the iOS version, and it only costs time to obtain the gems instead of "real money", it's nothing more than an annoyance, not a huge problem. (nicer would've been if the powers were pre-upgraded for you, based on how far you'd got stickering before).

Some general remarks:

In Homeworld the game/framerate is very slow/low, like you're playing online on an old 56k dial-up modem or something (gets smoother after all auto-collection is finished I think).

Weyworld is buttery smooth.

Overall I am happy with the update - I can play again, where it would previously just crash at startup or when sailing back to Homeworld from Weyworld.
