I gave in. I'm going to give Hajimari an attempt with the overlay. It's a bit cumbersome at first especially if you fuck the line advancement up and don't lock it where you're supposed to, but once you know what you're doing it's not bad. I've played enough Trails now to know what I'm doing in combat. I suspect quartz will give me a bit of an issue, but I've got the difficult on Easy.
Thinking back a year ago, I hadn't played any of these, and now I'm a junkie looking for my next fix, using all the methods possible to play.
I am still 100% buying the game when it comes out in 1.5+ years and it'll be an even longer wait for Kuro, but ah well.
I'm no expert of Japanese, but the translation seems pretty on point going off the limited knowledge I have.
I suspect due to the story structure of this game, I suspect Kuro no Kiseki will be a bit tougher to do with the overlay, unless they figure out a way to know which NPC you're talking to.
