I've just reached chapter 5 and can S Rank the relationship between Sumia and Chrom. Chrom is like level 15 and Sumia is about 11... Do the level/skills learnt affect anything for the children or is it just the potential of the character affected by the parents? --- http://myanimelist.net/profile/dude3991 PSN/Steam: dude3991
When they marry isn't as important as when you recruit the children. You can marry ASAP, and wait until the last chapter to recruit the children, and they'll be just as good as if you didn't marry until the last chapter.
Well, usually after two people have been dating for at least a year...............erm, I guess you meant in this game. my bad
Just make sure you have the skills you want them to pass down to their kids in the final slot before you start the children's paralogue. --- Official Horus of the Shin Megami Tensei IV board Official Walhart and husband of (F)Morgan of FE:A
