Not only last year, I have got three memories to share:
The first and best memory was in fall 2020: I had been reading all over the net that PZ was so difficult with building that I didn't buy the game because I thought I wouldn't learn it at all.
Finally I took the chance and got the pack, and I was as happy as a little kid could be finding out that it was exacly the game I was looking for for years!
But yes, learning how to build in groups etc, was a real pain.
Until about half of january 2021: Then the bell was ringing in my head ; oooooohhhh, is it working like thát? I was happy for weeks!
And the last one: finding out the Europe pack was so much more than expected!
