I've played through all the previous games now, and I've enjoyed what was on offer. The series started off a little shaky, the first game being fairly underwhelming imo despite some genuinely charming characters, but over time it saw significant mprovement. I throroughly enjoyed the sequels, so I have little reason to doubt the quality of this title. I'm also looking forward to, y'know, actually being able to understand the bulk of the dialogue, since the game can be quiite text heavy at times.
So yeah. I'm quite looking forward to this one. If they never go back and translate the initial games, it'd be a shame. A lot of stuff went down in the trilogy, establishing all the characters, locales and an ongoing story that culminated in a surprising conclusion.
