Abyss is a loooooong game. Lol.
Somebody versed in Tales correct me... sourcing wiki to help me. I've only played a few of these:
Phantasia — Wolf Team (later Namco Tales Studio), but key staff like Gotanda / Norimoto / Asanuma left thereafter to form Tri-Ace (who makes Star Ocean, Valkyrie Profile, etc.); released outside of Japan much later on the GBA
Destiny — Wolf Team with new staff; released outside of Japan
Eternia — Wolf Team; released outside of Japan but retitled as Destiny 2
Destiny 2 — Wolf Team
Symphonia — Namco Tales Studio (renamed Wolf Team); released outside of Japan; first with 3D view and features in battle
Rebirth — Namco Tales Studio; back to 2D battles, but others below have 3D battles too
Legendia — Project Melfes (not by Wolf Team / Namco Tales Studio); released outside Japan
Abyss — Namco Tales Studio; released outside Japan
Innocence — Alfa System (also not by NTS); only on handheld
Vesperia — Namco Tales Studio; released outside Japan
Hearts — Namco Tales Studio (?); also only on handheld
Graces — Namco Tales Studio; released outside Japan
Xillia — Namco Tales Studio; release outside Japan announced but pending
Xillia 2 — Namco Bandai (but with most of NTS staff)
Note that Yosh|to Higuchi was director on Symphonia, Abyss, and Vesperia, which are some of the better-regarded titles.
