There are so many new features and mechanics in PSO2 compared to PSU and PSO that I actually feel like taking a book on the game to just read through the entirety of it.
I find it easier to learn things this way and find it more relaxing than looking through a bunch of links on the screen and sometimes trying to find things over again.
But yeah I don't know about anyone else, but I might have to start printing out pages of information on PSO2 just to carry around and read during random times I am out or free while waiting for the next server opening.
I'm learning so many little bits and pieces everywhere on streams and forums and the twitter page. Even the game popup tips are super useful but then I forgot what it was saying sometimes haha.
