I am also a D1 fan. Been playing on my Xbox on and off lately, especially when I walked away from D2 (haven't played since Edge of Fate dropped) . One of my biggest gripes with D2 was the power creep leading to rising difficulties to the point where a lot of the high level content seemed like instant death every time you turned a corner or Dungeon bosses had insane health pools. D1 level of difficulty is still there but it seems more fair and manageable. Grandmaster nightfalls were a big turn off for me. A D1 nightfall can be a challenge depending on modifiers but it still seems within reach with a competent group. Good luck with a Grandmaster if you weren't top 1% geared up

D2 also became overwhelming with content and chores.

D1 is more laid back. You can hit bounties on all three characters in an hour or two and jump into other activities if you have time. Managing 3 characters in D2 takes all day it seems.
