I adore the first trilogy of DQ games but I'm holding off cause I don't like or trust SE anymore (plus, denuvo, ugh).
I will say, it's a better experience to play 1 thru 3 in order with no prior knowledge of what makes them a trilogy. Having 3 stand alone kind of misses that "oh fuuuuuuuck" realization I got to experience (and subjected a friend to, who has yet to forgive me lol). It's what made 3 one of my favorites next to 5 and 11.
I might pick it up in the near future. I don't have much nostalgia for the NES Dragon Quest games, but this one looks amazing.
If they remake DQV and VI in this style I will buy it in a heartbeat! And yes, I know V had two remakes already, but none of them are available on a modern platform.
