I actually quite liked the turn based option in might and magic. Normally you would walk around but at any point you could drop into turn based combat if you wanted to, it made it a bit easier. Similarly Eternal Sonata actually gained active battles as the game went on -- it started off as fairly normal turn based, albeit with a bit of focus on placement, and as the game went on you unlocked extra modes in which more and more aspects stopped pausing to allow you to press go (and thus you could miss them), you could turn it back to stock or any level you like though.A game can have both "action" and turns
That said I will still observe the distinction I made above -- if it makes no difference if someone else holds the controller and I just tell them where to move then it is turn based, if any aspect of it requires speed or dexterity or basically someone else playing would be considered bad form if I am doing it in competition or some kinds of speedrun then it is active.
