So, this game is pretty addicting! I've been playing the story missions, plus all the side quests and random encounters that appear, in an effort to keep everyone leveling up and improving their support bonuses. The relationship dialogue is a reward unto itself. There've been a few beats in the main story where proceeding directly into one of the sillier conversations seemed especially out of place, but that can't be helped in a game that let's advance the side stories at your own pace.
I used the one Second Seal I found to dual-class Chrom into a Cavalier, and because he retains all of his stat increases when resetting to level 1, he's swiftly growing into a god on the battlefield. It's a good strategy, considering that he's one of the few absolutely indispensible characters. He's also gotten married to
I'm also weirdly obsessed with Donnel, the pot-helmeted villager who can't take a punch without needing divine healing. I've played enough of the previous Fire Emblem
games to believe a character this lame wouldn't be included unless he secretly became a mecha-dragon lasersword badass at some point, so I'm working him up basically to see what happens.
Around Chapter 11 - 12 in the story so far -- feels like one of the best 3DS exclusives so far!
