The World Ends with You

Earthbound
Breath of Fire
Mario RPG
Shadowrun (takes a bit to get into, but it's great)

Dragon Quest 4-6, 9 (DS), The World Ends With You, Secret of Mana, cant think of any else off the top of my head lol

man, buy a wii and get xenoblade.
it is as good as chrono trigger in my opinion. both are tied in the greates jrpg of all time for me.

For DS - Dragon Quest IX:SSS, The World Ends with You,

+1

Earthbound is pretty good so you should give that one a try. It's like Dragon Quest but with a modern setting!

You should try playing the Dragon Quest games too if you are into those. Beware though they are very simple yet hard, they are quite traditional in every sense of the word. If you want you can play Dragon Quest 3 which is considered by the japanese as the Best Dragon Quest game in the series. On DS you have Dragon Quest 4 5 and 6. Dragon Quest 5 is my personal favourite, they are all pretty great JRPG's.

You also have Star Ocean which as an fan translation and it's an action RPG. It's fun but there is a remake on PSP so maybe you should skip that one.

There is Tales of Phantasia on the GBA! It's an action RPG too and it's quite great, you should give it a try.

You have The World Ends With You which is ok but it's kind of a mixed bag. Some people love it and some people hate it, it's on DS and IOS.

You also have the Shin Megami Tensei games on the SNES. Those ones have a fan translation and they are quite good but they are not for everyone. It's like the Persona games but without sim dating elements and an apocalyptic world. You also have Shin Megami Tensei IV on the 3DS, it's like the older ones but it is more modern and bearable than the originals.

Give a try to the Super Mario RPG games too! There are a lot of them and they are weird RPG's because you don't depend on equip or level but on the timing of your attacks!

You also have Final Fantasy of course! You can play the fourth game on the DS, the GBA or the SNES. The sixth game is on the SNES or the GBA, and you can play 5 on the GBA. They are all very good Final Fantasy games.

Anyway there are a lot to play! And these are the ones I can recall.

Oh I almost forgot, Xenbolade Chronicles (Wii) and Shin Megami Tensei Devil Survivor (DS,3DS) are very good ones too!

Chrono Trigger again. The game has 16 different endings.

PSX RPGs are better, but for SNES and DS, from what you haven't listed I'll recommend Secret of Evermore, Terranigma, Breath of Fire 2, Dragon Quest 3(SNES remake,) Dragon Quest 4-6(DS,) 7th Saga.
