I've never played a Fire Emblem game. I've heard great things about the franchise so I'll be playing the latest game in the franchise. I'm a fan of these types of games(FF tactics) but I'm worried that I may be getting into something that may be too crazy. Can any FE experts out there let me know some key things about the franchise and what I should expect from the 3DS game? Lastly, should I play any of the previous games in the series?
