where is Blazer when I need him
so what I've been getting from this thread so far is
either Tales of Hearts R or Xillia first based on gameplay similarities
probably Hearts R first since Xillia has more replay value if I feel like playing it again
and Graces F as the last one whether it's the better game or not (it's not on anyone's worst list I guess so it has something going for it)
???
what exactly do you need from me, just a response? haha
sorry been busy
as far as game rankings... ah right, only the three. in that case, I'd say Tales of Graces f, Tales of Xillia, and Tales of Hearts R, in that order. While Graces has even less of a serious/dark plot than Xillia, I personally think it's the most fun out of the three games. It has some fun characters/dialog of course but also the battle system, despite being different, is entertaining, it's a colorful game, and the music is great. I'd say Hearts R wins over Xillia gameplay-wise (that's mostly just a personal preference though), but Xillia is probably the better game as a whole due to having higher budget. It also gets points for actually having an English dub (something I value).
The thing is Mercurius, with you, I don't know which you'd actually enjoy more based on your own personality and such. I honestly don't have enough of a grasp to predict which of the three you would--thinking in terms of like, character personalities/depictions, story, etc. here.
If you're debating between Hearts R or Xillia, I'd probably have to say Xillia. Hearts R just feels like a lower-class game and an older styled RPG. It has the essence of a Tales of game but in some ways feels out of date and bleh. Xillia will probably be a slightly more epic and rewarding experience. Also, the other route hardly has any differences, but I suppose it has just enough to warrant another playthrough if you really liked the game. I played both and as far as I remember there are just some slightly different scenes and like two or three parts where the dungeons differ. And the opening is different and the battle music is slightly different. I think I enjoyed Jude's path slightly more (again, can't remember too well) but they both have their ups and downs, I guess.
Eh, if you have any specific questions, feel free to ask. My suggestion is probably Xillia (especially since I haven't even beaten ToH R), but that's only because you don't seem to want to play Graces F and Hearts R (which was mostly developed by another company, 7th Chord, TMK, and is just sort of lacking on quality/polish/effort on the whole compared to the mainstream console Tales of games, even if the battles and music were enjoyable from what I played).
tl;dr Symphonia or Vesperia is the way to go, they have the biggest fanbases, clearly they're the best games *shot*. don't ever play Zestiria, I did, just listen to the music, it's not worth playing. Xillia 2 is also bad, unless you love Xillia or become a hardcore Tales of fan, I really cannot say it's worth it to play TOX2. the older ones are too old, spin-offs are either bad, jokes, not localized, or just fan-service for Tales of loyalists, no real comment on those
