Tales of Symphonia - Was a beast of a JRPG and was the first time a Tales game made it to Europe.
Paper Mario TTYD - Best PM game in the series
Baten Kaitos - Quite tactical and taxes your improvisation and quick thinking in it's battle system, VA's were something that really needed better work though.
Skies of Arcadia Legends - Quite under appreciated tbh
Phantasy Star Online Ep 1&2 - Must have sunk hours into the co-op with my brother and friends.
Fire Emble - Slick as always.
