Love rune factory series, never played the others (kinda want eteian odyssey tho)
You have Arzan Legacy on your wishlist. Be warned the game may cause feels at end game
As for Dual destinies...I STRONGLY recommend playing the earlier AA games first as the game may contain spoilers for it. Also PL vs AA is good
Currently I cant think of any 3ds gambles (expect fire emblem but I had heard so much good of it) but the ones that pop in my mind currently are - rune factory 3 (ds) - another code R (wii) - last window secret of cape west (ds)
I love Rf and Lw (altho never finished Lw), another code was medicore (also it wasnt exactly a gamble but more of 'why not')
Mages were my faves to use along Lonqu, Say'ri,Owain, Lucina (my powerhouse), Tiki and Anna. I played my first playthrough on casual mode and ended up marrying Cheom (Accidentaly...if I had chose I would either have married Lonqu, Libra or Frederick <3..or possibly even that pimp named Virion) .I started a playthrough on hard + permadeath on mode as guy... i am stuck on chapter 6 I think... (playing it as guy ans trying to marry either Tiki or Anna)
Libra got completely separated from the group and died. He was at the very end of a battle. His dying words were something like "Even though I am gone, please do not let my friends suffer the same fate!" I was so sad.
I lost Cherche in my first battle with her! Damn archers! And their bunkers. And Archie Bunkers!
I do have to study, but leveling my characters and making gald is actually easy to do while studying. I can both at once. Did you see those items in the shops that cost way too much for anybody to buy?
