Oh OK, then I'll post one more -
Relaxing is the first word that comes to my mind when I think of playing this game. I'm fairly certain (as I've managed to solo all red/blue/gold content short of hami/msr/incarnate trials) that nothing really poses a mental challenge to me to create too much cortisol in the 🧠. Now if I wanted to feel challenged, I've got avenues for that too in this game. For example, I'm currently running a deathless, street sweeping only, drops only SENTINEL (I assure you I'm not crazy 😜). It's at Level 8, I'm doing Kings Row right now, but I really want to start the first hazard zone (Perez Park). Only travel power is Hover, though I did snag Athletic Run from P2W so I could have an escape power if need be.
I think that sums it up. Relaxing when I want it to be, challenging when I need it to be.
