Checking your mood is important. The rest doesn’t really matter. The most I’ll do is check my internet, especially if I’m using hotspot from my phone, just so I don’t get disconnected at a crucial moment. Right now I’m playing on 1red-au.com, and it’s super straightforward, no prep needed. I don’t really see the point of getting ready for it, 'cause no matter what, it all comes down to luck and randomness anyway.
