I love FireEmblem. I have over 100 hours total (saved) game play on TSS. I hope they make a DS & Wii version. Using the touch-screen & motion sensitivity to move characters would be so amazing.
They have made the Wii version already. Fire Emblem : Radiant Dawn. I loved the Fire Emblem games and trying to find a Fire Emblem: Path of Radiance for the Game Cube. It's hard to find in stores.
Their is also a Fire Emblem for the Game Boy advance but you can play it on the DS though. It's called Fire Emblem: Sacred Stones. I've played and beaten it every difficulty, with every route, with every character alive and maxed every with highest class. Totally wasted a lot of time of my life on that though .
