I woke up a couple of days ago to find a lot of notifications on DCity that I got multiple student cards. Wasn't expecting any so not sure what was going on.
Here is just a subset of the announcements. All in all, I now have 48 students which is an interesting change because for one, it increases the popularity of the city.
And that creates a bonus for the population. So much so that I have swung from an 80 worker shortage to a surplus of 40+ workers. There is also a tax relief for the city that each student brings. I now earn more from the tax refund than the actual earnings of the city.
I have also moved my SIM from the game to the SPS:SIM pool on BeeSwap. From what I observe, this still counts towards the SIM power so it is good to earn some BeeSwap rewards as well.
