If you were doing scanning 12 years ago, there has changed quite a lot (i remember this old scanning system, i found it awful).
I made a short listing in the other “came back” thread (the more ranting one )
But the main question should not be “what can i do in EVE”. It should be: “What do you want to do, and does EVE has it”.
There is way to many that you can do in EVE. The Big Honking Chart from Mkikaden Tiragen is showing it. And this one is a bit overfilled and outdated (it is from 2016, if i see it right) at the same time.
