I've been thinking, with Fable III being tactile and building on relationships between co-op partners it struck me; what happens when the two players veer off onto a love story?
Will Fable III's plot impinge? Will it leave us free to roam? How long and what is there to break our supsension of disbelief?
How immersive will it be? Would I be waylayed in forging a weapon as a gift for my in-game fiancee, or picking flowers to give them or going for walks and slaying balverines?
RPGs are rife with love subplots and romance side-quests (Mass effect made a big build up then bamn about 5 secs of blue buttock that was terribly arkward), gaining girlfriends in Persona 4 (someone i know playing their 3rd playthrough to get all all the romances) and Dragon Age (which I loved for including LGBT but loathed the characters...)
