To date, this is the hardest challenge I've done. Took me 78 hours, and those hours were intense. My heart didn't allow me to play for more than 1 hour per session.
Previous PB: 450. Now: 618.
Normally, I would record a replay since the game supports it really well. However, this one is special, so I try to record it live. Until now, I have deleted hundreds of GB of recordings. Still, I think it's worth the effort.
