Tales of Symphonia is one of my favorites, beat it 5+ time so that is number 1 in the last 20 years. Persona 5 is either my 2nd or 3rd favorite of the past 20 years, Tales of Vesperia is close. Even though Persona 5 is in the top 3 for me, it is my 3rd favorite Persona game after 3 and 4. Ni No Kuni is up there as well.
