It's a good thing you didn't sell the games. Even if you're bored of Fire Emblem now, there's a big chance you'll get back into it, and then you'll most certainly have regretted it.
I'm not really the best person to give advice on this though, I collect games and I rarely sell them or trade them in, (only if I really didn't like the game, but it has almost never happened to me before) because I like to replay my older games, and they have a certain value, as well.
