Well, I am a pretty big fan of the Pokemon Mystery Dungeon series, and thus I would likely be a fan of Last Mission as well.
It actually looks pretty fun, especially with the way the dresspheres are implemented into it. I hear that the final boss (the 80th? floor) is actually really hard as well. Can't wait until the English footage, or at least the Japanese footage with the offical English subtitles, is released. I wanna see/hear how they handle the dialogue and voice acting after all these years, since Hedy Burress and Tara Strong have obviously improved since then.
I have to admit though, while I enjoy all of this not-so-subtle TidusxYuna fluff in the cutscenes, it makes X-2.5 and Will seem incredibly... off, and actually pretty eerie. We go from Yuna gushing all over Tidus, in front of her two closest friends mind you, to her not even kissing him when the two are most likely alone (though Yuna thinks otherwise). Granted, the 2 latest translations from the novel doesn't make Tidus and Yuna seem
as OOC as we had previously speculated, but maybe's there's more going on. Those Japanese reviews on Amazon which said that they hated Yuna in the novel, couldn't have been because she was a little stand-offish. Don't forget the amounts of sympathy for Tidus, as well. Something must be seriously wrong in there; why else would the novel gain so much negative feedback? We, for now at least, have already debunked the necrophiliac elements and Tidus getting treated like a spayed dog. (It's a shame the blitzbomb thing was true, though...)
Nevertheless, Last Mission is interesting, especially when you look at Yadonoki Tower's design. There'll be fanfiction-galore when this hits the West, I bet. As for the inconsistent Yuna portrayal... well, the only thing we can do is wait for KaminaSan to receive her copy of the novel. She is our translator, after all.
