Fire Emblem: Sacred Stones.
Man, I missed playing this game. ;~; I'm playing in Normal mode, and I chose Ephraim's side. Right now I'm in the chapter where you'd have to fight Selena, which is pretty tricky to complete, because obviously you'd have to watch out for her long-range Bolting spell, as well as moving as fast as you can to the villages before the Brigands destroy them.
I haven't promoted much of my units yet because I'm waiting for them to reach level 20, so that they can get whatever stats that they need before their official upgrade.
