Back After a 2021 Hiatus: So Much Has Changed, Need Some Guidance!

Hey everyone, I’m finally back to the game after taking a break since 2021, and wow—so much has changed! From QI and GBG to GE Trials, new avatars, settlement 2x2 buildings offering more boosts than 4 of my event buildings combined... it’s a lot to take in.

I currently have two cities: one in the Future Era and one in the Industrial Age.

My question is: should I focus more on my IA city (since I still have my OF Torturettes and FE Hovers) or put more effort into my "main" city ?

I'm a huge GBG fan, and with all these changes, I was wondering if it might make more sense to focus on my lower world to get better GBG rewards.

Also any suggestions on building setups, GBS, or general strategies? Appreciate any advice you’ve got
