A game that ISN'T A REMAKE.
FE2: Villager class was nice.
FE4: I haven't played but I hear there are a lot of cool classes.
FE6: The abundance of units.
FE7: Difficulty of this game was good and multiple endings was nice.
FE8: The trainee classes and the branch promotion.
FE9: Support system, no FoWs except on hard mode, an interesting personality for every unit and promotion.
FE10: A minimum of 1 stat per level up.
Obviously I don't want ALL OF THIS at the same time though. XD It'd be too much but most of this are things I like.
I forgot what fortune does... *is feeling dumb* I haven't played FE in a really long while.
For corrosion, I agree... the only time it'll be useful is if you want to boss abuse but otherwise... a waste of skill capacity.
I haven't ever killed him. :( But I do attack him for the exp. But I just open the door in 22x since I prefer having silver weapons and because they're easier to kill.
Best: I don't like most gaiden chapters but I'll just say chapter 18x FE7(the one where you first see Kishuna) since it was kinda fun.
Worst: Maybe 22x FE6, I didn't like it much... too many status staff users, walls, traps and all.
