Radiant Dawn:
Recruiting Stefan is just as dumb as it was back in PoR
Support System was ass
THEY BROUGHT BACK THE SHITTY BRIDGE CHAPTER
Dawn Brigade has a difficult time gathering EXP and resources, rendering some of them flat out unusable.
Some units suffer from poor availibility (RIP Tormod)
Sephiran's recruitment standards (would've been nice to have a little hint)
Titania easily, both as a unit (those bases) and a character. Oscar is also pretty useful on the battlefield and comes with the same availability as Titania.
Some of my favorites:
ROBIN
Sumia
Chrom
Lucina
Morgan
Tharja
This being Awakening, just about any unit can be good if given enough resources (especially some of the children), but it depends on whether you feel like doing any post-game DLC or not.
No incest in FE13. The closest thing you'll get to that is marrying Owain to Lucina and/or Chrom's other child, but even then, the localization changed it to "Companions".
I haven't gotten around to setting up a DS Emulator quite yet, so FE11 and FE12 will have to wait. I've been meaning to start FE5 for a while but never got around to it.
I needed to change my pants when this song showed in in-game. It's a shame that it only plays during a brief moment before endgame though.

Rutger easily since he and Milady carried my FE6 team. Joshua is also pretty cool in my book.
I've always liked Marisa's character as well as her sexy design, but I've never found her to be at all that useful from a gameplay perspective.
