Not perfect, but pretty darn close to it.
Fire Emblem is an excellent series of games, but this one is one of the best games. Everything about it is excellent, from the graphics to the actual gameplay. The addition of the custom weapons and the Laguz make this game more varied than other games. Plus, there is actually an inventive to go through the game on a harder mode once you've beaten it once...
This game isn't perfect. The characters tend to be pretty unbalanced, but that adds to the challenge. Also, some missions are incredibly long, and it can get frustrating if you don't want to lose anybody (once they die, they're dead!).
Still, I really liked this game. If you have a Gamecube or a Wii (once it comes out), play this game. It stands out as one of the best for the wee purple box, and it is a nice, long game that will keep you hooked.
