Fire Emblem Radiant Dawn

The most underrated game in an underrated franchise (Before Awakening was released)
It is regarded as the hardest game in the franchise
Most Fire Emblem fans prefer the other games

Despite that, it is my favorite game of all time, in my favorite franchise of all time.

Is Radiant Dawn really an obscure title? If it is, it makes me sad. RD was one of the best games in the series.
