I'm both hoping and dreading for this release. On the one hand, they said they actually are trying to fix up the story by adding in some (though probably not all) of the missing parts of it. There might also be new side missions, possibly new alien species to join NLA, and improvements to QoL (such as actually explaining how the various gameplay systems work so you don't have to look up a guide). That might make it worth playing again.
On the other hand, I'm doubtful they will fix all of the flaws, especially because that requires rewriting. Particularly, the less likeable side characters (mostly non-story, thank goodness) could use some better characterization, and various bits of dialog could be written more naturally. And Tatsu needs a total rewrite; he's the only character in the game that comes close to being as despicable as the cast of Xenoblade 2. Unfortunately, I don't have high hopes for that much work to be done to really improve the game.
Don't get me wrong, I thoroughly enjoyed playing XCX when the characters stopped making shitty repetitive jokes and saying "there's something about this planet" for the Nth time. And on some level I do want to play it again. I just don't want to have to listen to them yap like morons again.
