Yeah I do want to play the Nier storyline leading up to Automata. Supposedly the chain goes Drakengard 1 -> Nier -> NieR Automata. Mostly the performance is pretty good on Drakengard on PCSX2, but occasionally in big fights I get brief slowdowns where the music turns weird, and I know that's not the PS2 but the emulator causing them. Plus I have heard Persona 4 is pretty bad on PCSX2.
