From the little I played it seemed as if RtiF plays the same as Legends. If you like the way Legends play, as I do not, you will probably like RitF. Unless, of course, you get the same crash bug as I did. I reinstalled, redownloaded and reinstalled, and still had the exact same crash. It came about an hour in, so that is as much of RtiF as I have played.
Unfortunately for me, I bought the addons for Legends without playing it first.
If you like the play style of Legends, and can avoid the bug I had, you might well enjoy RtiF.
