I think ZX is SUPPOSED to be the "ultimate power form" on the player's end (storywise, anyway), I just wish they'd given it more varied enhancements instead of just offering one new attack and nerfing the rest of the game's arsenal. The form is basically Z1 Buster/Saber Zero with a superior roll but otherwise crappier saber, no dash roll, damage barrier mechanics tweaked to allow boss raping, and the buster shot tweaked to allow stage-enemy raping.
Complete and utterly disagreed, Flame. ZXA > ZX in all respects.
One cannot deny that ZX > ZXA in arsenal (save for Vent's Rising Fang, anyway). Otherwise, it's a matter of opinion.
For the most part, I found ZXA to have an all-around superior presentation and variety (not to mention LOCALIZATION, you lazy bastards who silenced the first ZX), but it may not have been the best sequel
. Maybe they thought they were doing something clever with the whole lack-of-numbered-game thing, but I think reducing Vent and Aile to NPCs with Model ZX as an A-Trans was uncalled for. They could have at least been unlockables.
And of course, there is no "super form" to take the place of Models X and OX. Evidently unused life gauges suggest they had planned otherwise; they should have stuck to finishing that. Would have went a lot further than GEM BUSTING, that's for sure.
There are of course, numerous improvements that one shouldn't ignore. Perhaps most appreciated is the ability to rematch non-animaloid bosses in the minigame menu (although earning that right through Survival Road is a hell of a time).
Side-quests were a mixed bag. The organization of the quests themselves was improved, but the one-way Trans Servers made completing a lot of them rather tedious. Chip distribution is also horrid as half the game's library isn't even available until after you're on a Clear file. In that manner the game demonstrates as much as the first ZX why New Game Plus shouldn't have been axed.
