Well, if I'm being honest, I didn't play enough of Alliance Alive to get a good feel for the system, it was mostly the text wreaking havoc on my eyes that turned me off from it. Here's an example image from their site that shows what I'm talking about - the blurry outline behind the text at first gave me a headache and made me feel dizzy:
Well, what do you think we're gonna do next, report back to dad? No, of course Ursula is going to drag Galil with her to the museum. If he doesn't go with her, she'll just go by herself! Fine, fine. The museum is our first dungeon - ignoring the youma at the front who won't let us inside, Ursula uses her symbol arts to open a side-route (blast a side-route through a wall more like it, but details, details...).
Now I know it's chuuni as hell, but I thought this was so cool. Whose doesn't get excited when you have a blind character with an awesome headband/blindfold? They also went the less common route of the girl being the one who protects someone. Thanks to her symbol arts, Ursula can still sense her surroundings even if she can't see them, so she's not leaving our party (and she absolutely refuses to leave, regardless). Galil promises that somehow, some way he'll find a way to let her see the blue sky again. Actually, she's not physically blinded, just magically blinded, so if we can find magic strong enough to counteract the mazoku's power her sight should be able to be healed. That's apparently no easy task, though.
I have a good feeling about the game so far. Part of that may be the fact that later on, a foxgirl will be joining my party, looking at the character list on the game site. Having any sort of cat/fox/other 10%girl in it is enough to get me to buy almost anything.
The battle system I need more time to play with, but it seems interesting enough with the formations. Especially now that I have 4 characters, there are different formations I can use that give various characters bonuses to atk/def/spd/heal depending on where they are.
