In my previous DCity post, I touched on how I sold a Voice To Skull Card for around 30,000 SIM. I had kind of given up on the technology card strategy up till that point. Clearly i had the wrong idea.
It isn't about frequent selling of the more common cards. Instead, it is about the low probability rare ones. So with that in mind, I am refocusing on education and trying to score one of the rarer ones.
The first step to increasing my chances is to make sure I have unlocked all the technologies. The Research Center is hard at work and I only have 6 more to unlock. I will focus on Utility, then Economy and finally, Health.
I am not sure why some of these technologies are made so rare when their benefit isn't apparent. Increasing a Garbage Dump's earnings to 15 hardly makes up for the popularity hit in my simple mind. Still, it goes for a pretty penny.
