Really have to agree with your assessment of Finn there, now that I've poked more at 4 and 5.

What, that he's not into chicks? That isn't, shall we say, a popular view, but it sure seems to me like the Occam's Razor conclusion to draw there. Mind you, maybe we're supposed to find Selfina's rant at him amusing and not take her seriously... IDK.

I really did find nearly every match in the game itself wholly unconvincing. Quality over quantity, please.

I still get the warm fuzzies from how FE2 handled relationships. It's minimalist but it works for me.
