Yeah, actually I lied.
Gale is only the START of the game's awesomeness. Then you get the Command Function, which allows you to control your teammate's special abilities, and yes, the more you level your teammates up, the more abilities they unlock. You can order your team to head back to the nearest cure ring, or send a buttload of awesome moves your enemy's way.
The mix of party members keeps things fresh, as does the game's continuous spin on the battle mechanics. The boss battles are always unique, and feature different strategies for maximizing damage and being a bamf.
Thank you, thank you, THANK YOU XSEED. I was very skeptical about the battle system in this game- I was worried I wouldn't take to it that kindly and, like broodwars, after going through the somewhat weak tutorial levels (the tutorial levels arguably go up to like, chapter 4), I still wasn't sure. But when the action starts and things begin to pick up, the game gets much more fun, and the locations do, as well. The warehouse in the tutorial is very dark and difficult to navigate, and I should also mention that most of the game's set pieces are a little compact in size- but that doesn't make them bad in any way. In fact, I really like how the game is so much smaller in scale and scope than say, Xenoblade. It makes you appreciate the really large areas much more, like the hub city, but also makes things way easier to explore and maneuver. I think someone may have mentioned this before, but where Xenoblade wows you with pure scope and magnitude in both features and geography, EVERYTHING in The Last Story is smaller but packed with intention. It all serves a purpose- from the stone pillars which are your cover, to the grinding circles for repeated encounters, and the spells that have vastly different effects, and the number of interesting equipment options.
Also, broodwars, you may find yourself going back to automatic attacks eventually, though in some boss battles and junk it's nice to be on manual. When there's a lot of enemies and time is short, I find myself planning the squad's actions and making sure they're covered with different button presses, and it's nice to just have the option of walking up and wailing.
