Day 1
What went right: I was able to download the 59 MB patch that unlocks GTA Online and install it. Also, on my second try, I was able to create AND save my first character.
What went wrong: Pretty much everything else, as expected. For some reason, despite being the creator/leader of my crew, I showed up as not being in a crew. My two attempts at doing the opening race (after the introduction) were unsuccessful, as I got stuck on "Starting Session" the first time, and "Waiting for Other Players" the second. After that, I called it a night on GTAO and went back to the single player game.
