I’ve played Diablo 1 and world of Warcraft which is slightly similar, but just tried d3 a week ago. I play most games on my switch, I grabbed the eternal edition a while back. The spec system looks really basic, but it gets fairly deep with runes and legendary items. What amazes me the most is the speed, there are a ton of graphical effects popping on high level gameplay, and zero slowdown even with 100+ enemies casting spells constantly. I’ve maxxed two characters so far and gearing them now.
Just stay clear of D4 it’s a complete train wreck.
