I've heard nothing but good things about Bravely Default, but I also haven't actually played Bravely Default, so I don't feel right recommending it. Knights of the Old Republic's battle system is kind of dated and not the most exciting, but is still fun, and while Mass Effect 3 has some story woes (and I don't mean the ending) the overall gameplay is still enjoyable. Be forewarned, if you enjoy the story elements more than the action in ME, 3 tends to be more action oriented.
