Ahh, Tales of Symphonia is not for the PS3 (though there are rumors that they might remake it or report it for that system). It's for the Gamecube. But if you wish to get a Tales of game for the PS3 there is Tales of Graces and Tales of Xillia.
PS2. You were better off getting the 3DS version considering it's a newer system and has more games coming out for it anyways. But if that's the case Abyss is going to be the only one you'll be able to play unless you have a 360 or a Wii.
