Thanks!
Actually dCity just seems complicated, but when you start to play it's very easy to understand. Of course there're some tactics and strategies everyone can choose. You only need to keep your citizens in balance employed / unemployed.
The game play in the beginning is somehow slow, but if you have some free hive to invest you can progress faster.
Best advice is to start with income cards only, not looking at education and creativity. There are some buildings with very good ROI. For example the Ad agencies, weed dispensaries etc... which will give your investment back after 100-110 days ;)
Overall, this game is one of the best passive income ways I've found during my crypto adventures, dating back to 2012.
