Really? I was reminded of Final Fantasy Tactics, and immediately fell in love with the Series(Laharl <3), Disgaea D2: A Brighter Darkness being my first title. Haven't played Fire Emblem that much, recently got the Collectors Edition of Shadows of Valentia, but due to lacking time right now, didn't play it. Hope it isn't too hard, the way you describe it makes me a bit wary :-(.
Rune Factory 4 is the better Harvest Moon for me. So addicting ^_^ Dating and Marriage, super customable Home, large farm, Cooking and Crafting, Festivals, Events, so much more. I even like the combat.
