4. Spyro the Dragon ( ahh childhood memories... I still get a rush when I do that double speed charge ramp to glide to the 3 chests and egg guy on the far platform...)
3. SO3:TTEOT ( the weapon crafting and amazing amounts of damage I could do, and extra content was what made me like it... even with the horrible twist... :/ )
2. Legend of Legaia ( Played this continuously... and was an incredible story and game play for a ps1 title... and the characters actually wore the things you equipped on them!.... also, good music, and fun combat.)
1. Chrono Cross (The music and gameplay and story are things of legend to me. Even now I play it at least once a year... it will be the game I pass on to my kids)
Honorable mentions: all the FFs, Persona, SOTC
