One thing I really love about Fire Emblem is that though there is a strong simplistic quality to it, it's rather complex in its battle system. And by that I mean how they use swords, sorcery and transformation in order to change things up.
Swords, lances, axes, bows, numerous elements of magic, and beings transforming into other beings, it's all great. And with pros and cons to each, you have to be careful with how you use them, and who you use them against. Cause with permadeath, a wrong move can be fatal, and who wants that?
It would have been so easy just to make everyone have a weapon, but by growing it beyond what they had? They made a deeper game with greater strategy and more replayability. Nice job Fire Emblem.
