This was my first fire emblem and having played all the other ones available in english and one fan translation, I can safely say I am the fan of the series. I really enjoy the way they create worlds consistently with great back stories and characters.
The gameplay is simple to learn and difficult to master. It can be infuriating when you've moved someone a space to far by accident and you get severely punished for it but it happens far less than in many games that get far more credit in the west than this.
The cutscenes are good and there are one or two excellent pieces of music in the soundtrack. The graphics aren't anything special but if you're playing computer games for graphics, just buy GT5 or Avatar on blu-ray and never watch anything else.
Some criticisms I've read of this are just ridiculous. One was not enough new characters. It's a direct sequel? If there were any more new characters you may aswell not have it is a sequel. Should we take John McClane out of a Die Hard? Not using the Wii controls. So? Smash Brothers doesn't use the motion sensing either.
Not my favourite fire emblem, but it's not far off. I think it's an extremely enjoyable game that far more would appreciate if they gave it a chance. One of the 3 reasons I'm really glad I own a wii.
Also Ike is awesome.
