Every decision you make comes from how you understand the game. The decision you made can vary vs opponents. We all made those crazy moments where you'd think it reverses the battle to your favor but made it worse. It's alright.
It's safe to say DMC5 > Nier Automata, despite Nier being a much longer game and a big world experience which is what I liked about Nier. Think the only DMC game that was similar (kinda) was DMC1 but that was back on the PS2.
