I actually really enjoyed Revenant Wings. Up until the gameplay just quit.

I was doing all the missions and sidequests, leveling up my stuff, and generally just enjoying Ivalice, despite numerous little flaws. Then I got to a fight, and wound up against a boss that was simply unkillable.

I think it was Ultima. But, anyway, here's how it played out: I sent a ton of summoned monsters against her. She used an attack that wiped them all out instantly. So I tried again. It happened again. I send only a few against her, keeping the rest in reserve. She doesn't use the ability, kills them herself, and takes basically no damage.

You can't whittle her down, and you don't have nearly the control scheme needed for successful micro management. She's not the only boss that does this. Basically all of the endgame bosses have an ability that just ENDS your entire army with no questions asked. Max level? Doesn't matter. Built up a force for half an hour, with top tier foes, properly aligned elements and everything? Doesn't matter. Instant death. Deal with it.

The way the game teaches you to play the entire time is thrown out the window and you are left with basically no alternatives because "group up and attack en masse" is basically all you can do with that control scheme.

The boss couldn't kill me, and couldn't make me end the mission, but there was nothing I could do to win. I turned it off and completely forgot about it.
