In order of favourite to slightly less favourite:

1. DDR/Pump It up!, Ez2Dancer. (I can't decide which one I like best)
2. Soul Calibur 2 (only 2 because 1 doesn't have Cassandra. And Sophitia is NOT the same as Cassandra. She is a completely different styled fighter and you have to use her in a completely different way)
3. Final Fantasy VIII
4. Tales of Phantasia (SNES, because Arche is cuter in 2D)
5. Chrono Trigger
