I absolutely adore Ar Tonelico II so it took a while to adjust expectations down for Qoga. There are still many good bits here and there but it resembles a pizza someone dropped on the dirty floor. It still looks good and you can eat it but the grime really turns you off.
The hymns are sublime as always and some pieces are the best in the entire series, the BGM is either good or at least functional, even though I prefer the other games in this regard. That's where my praise ends though. The gameplay remains the JRPG paired with Visual Novel thing, so I'm fine with the static character shots over a background and textboxes approach. The 3D character models during normal gameplay though look awfully dated on the PS3 and the character (or rather costume) design is just horrible. As a JRPG fan I have a high tolerance and the other games weren't tame either but when one character runs around with different-colored stockings and nipple tassels while another character essentially just wears bits of masking tape on her chest it just gets stupid.
Speaking of characters, that's another low point. The main character is completely insufferable and while Lyner was a barely alive cardboard-cutout and Croix a bit of a wet blanket, at least they were inoffensive. Aoto on the other hand seems to be a amalgamation of the worst possible anime hero cliches the writers could come up with, always going on an on about being a guy, the man, protecting the female death robots dishing out 100 times the damage he does. And he constantly fails at protecting them too. There is a surprising amount of cut scene stupidity and it usually revolves around Aoto; A giant killer robot? No problem. An old guy choking him? Whoops, hands tied. And he's schizophrenic too; One girl he treats decently, the other much more likeable one he bullies for absolutely no reason other than a poignant reveal waiting down the line. Saki is a completely bland "moe" girl, one main character is barely in the story and another one is quite interesting but only appears when you're two thirds through the game.
The story takes a long time before it develops at that point too, until then it just strings a long series of "save girl x/world from y" quests together like this is baby's first RPG. It's ultimately harmless, has fun parts and gets nice at the end but it's nothing to write home about. Neither is the combat for that matter, while the AT II combat required at least timing and could be challenging, this is just a bad knockoff from the Tales series; run to the same 4 or 5 enemies, mash attack button and cast your overpowered one-hit-kill attack spell. Rinse and repeat. The final boss has 5 stages, 4 of which are exactly the same with slightly different background and music. Why?
Cosmospheres and Item Synthesis are fun as always, the westernized translation can be a bit grating but is at least mostly accurate so what's left is a halfway decent game. If you want to play an RPG and already went through the better entries in the PS3 library then it's definitely worth a try, as long as you can get over the whole pointless stripping mechanic and the tedious, unchallenging combat. Or better yet, dust off a PS2 and play the other Ar Tonelico games which are far superior to this mediocre ending.
