I have a lot
Pokemon- for obvious reasons
Lunar 2- Very unnoticed but amazing game with great story mixed in with some humor, great characters, simple but fun gameplay with impressive CGI for the Playstation era.
Tales of Symphonia- fun gameplay, great story, most the characters are likable, and wooo, co-op! =D
Mother 2/Earthbound- very off the wall RPG, getting a lot of popularity now, but back then kind of overshadowed
Golden Sun- Not as good as Pokemon, but a somewhat overlooked handheld RPG series. The visuals are amazing for the system, the story was very fun, and the custumization was fun to mess around with, however kind of made the games a bit too easy (only downside lol)
