Yea The last Story and Xenoblade and Pandoras tower were great wii games i recommend it to 3veryone to expirience this masterpieces

KH also has permanent button-mapped attacks/commands. Name me an Action-RPG that has been labeled as such that doesn't have permanent button-mapped (or key-mapped) attacks. 

In a (standard) MMORPG you can use hotkeys to designate an skill, but it can be any skill you want (like Xenoblade), and it only is utilized for skills, not basic attacks. Most people don't qualify the MMORPG system as Action-oriented unless you have full control over your character and you have a few permanent attacks on a few keys, as well as a dodge key, sprint key, etc. Xenoblade doesn't have this. The only ARPG feature it has is that you can move during combat, but so do many non-Action Real-time RPGs and all MMORPGs. You still have cooldowns for certain skills like in an MMORPG. 

How is XC's system different from a typical MMORPGs? In fact, with premonitions and combos XC truly does have full turn-based in its combat, unlike MMORPGs. I can't dodge, parry, block, or anything manually in XC, and my basic  attacks are auto-scripted (all I have to do is be near the enemy and I attack) like an MMORPG. In an Action-RPG I must do all of these things manually. I don't attack unless I press a button to do so, and that button is dedicated to attacking. Another button is dedicated to dodging. Another to parrying/blocking, etc, etc. 

The combat in XC is much closer to WoW than it is to KH or Diablo. 

It was the swansong of the wii

Diablo and PSO also does this and doesn't have dodge, manual parry or sprint and is still an ARPG, KH doesn't have a permanent attack button you move a cursor over menu selections to determine what action the mapped button does, this is essentially the same system XC uses. XC is action based because you perform an attack and it comes out with out being subject to any turn based system, the interface menu is only there to allow multiple abilities and commands to button maps much like KH, this is why XC is classed as an ARPG while MMORPGs like WOW use a hidden atb like system when performing actions.

Premonitions hardly change anything in fact it backs what I'm saying as that's the game's solution to try and bring the strategy turn based games have as that's lost in in ARPGs.

Not as good as Xenoblade IMO but completely worth the pickup if you like the genre.

I plan to get Pandora's Tower soon. :D

Sadly, I haven't gotten to Lost Odyssey yet. Plus, some people might like it more, some people might like it less.

How does the OST, plot, and battle system compare?

There are not as many soundtracks in TLS than Xenoblade, but they are just as good as Xenos.

Plot is pretty good although kinda linear and predictable. Still satisfying though.

Battle system is very unique but has some issues. You can overlook them as they are only minor.

I never said that ALL of the aforementioned are necessary, just some subset of.

In Xenoblade I can't do anything except auto-attack, go through a menu to choose a special, or move around (limited.) In diablo each attack corresponds to a click of a button. In Kingdom Hearts I can strafe, block, use magic, attack, all with a single or set of  buttons (at the same time) (no menus required except for switching out a skill for another one.) KH just incorporates its attack option as the default in its menu system. If it didn't have the attack option as the default and instead chose to correspond attack with "X" then nothing would change. 

XC has the same exact system as MMORPG's. You still haven't explained how it doesn't. In XBC you auto-attack as long as you are in range. You can then use skills that have cast times and cooldowns that are in a menu (Xenoblade) or on a hotkey bar (MMORPG.) There is no difference in that aspect between MMORPG's and Xenoblade. I click the hotkey or I choose the skill and there is either a cast time or it is instant. Then my skill is on cooldown. If I want to limit aggro my character can keep auto-attacking. If I click a skill in an MMORPG there is no ATB timer that my opponent has precedence over me. It depends on the cast-time and cooldown of the aforementioned skills. If I had enough mana and everything was off cooldown (let's say these skills don't have cast times) I can use as many skills as I want in as short of a time as I want. However, I can't do things like strafe, dodge, block, parry, or basic attacks by a click of a button in both scenarios. 

In an action-rpg on the otherhand, each button corresponds to "attack", "spell", "dodge", "block", etc and I must press said button in order to enact it on screen. There is no auto-attack. There might be cast-times or there might not be. There also might be cooldowns for certain skills, but most skills are limited by mana in ARPGs. I can dodge attacks that are coming my way by not being in the line of sight. In a game like XBC this is limited by the type of attack and its range, not by any physical proximity (the attack doesn't go infinitely until it hits something, for example if it were say magic.) There are very few action elements in XBC. You don't have a set button to attack, block, dodge, and/or strafe. Everything is either auto or done through menus. You can move around and jump, but both of those a pretty useless besides running away from a battle or leaving the range of an attack (jumping doesn't stop an attack from hurting you if it is on the ground, for example.)
