I've only played Abyss, a bit of Symphonia (waiting for the PC release to play it for reals), and Zestria. I want to play the others, but Destiny and Eternia are practically impossible to nab without paying an arm and a leg summoning them with a human transmutation circle @_@
Abyss is a game I got on the 3DS and it was the best thing I bought in a long time. It made me cry so many times ;w;
