Are you just trolling? You don't even have your own list!
Because I'm not an expert on the topic. And I already know what I know, I'm here to learn what I don't know, or might not know. And perhaps others are as well?
And where's your list by the way?
I didn't mean to be rude, it's just a really massive undertaking to make a top 10 for every generation in a single thread, ya know? It's also common to start with your by filling out your own list, which has a way of showing you're serious. Perhaps my perception is skewed because this is the kind of thing I might do ironically making fun of how prevalent list threads are.
As a show of good faith, I'll attempt this here massive list... when I think of JRPGs, I don't tend to think of action RPGs, so I am excluding those... tactical RPGs I do count though.
8-bit era:
1. Dragon Quest IV
2. Final Fantasy II
3. Dragon Quest III
4. Final Fantasy III
5. Final Fantasy
6. Mother
7. Dragon Quest II
8. Dragon Quest
There are many more JRPGs not release in America that are probably good, but I've never played them enough. In fact, this list is probably every 8-bit RPG I've played (enough to rate).
16-Bit era:
1. Final Fantasy VI
2. Chrono Trigger
3. Pokemon Gold/Silver/Crystal
4. Super Mario RPG
5. Lufia
6. Live-A-Live
7. Dragon Quest V
8. Final Fantasy V
9. Lufia II
10. Final Fantasy IV
64-Bit (Maybe not accurate, N64/PS1 era)
1. Dragon Quest VII
2. Final Fantasy Tactics
3. Final Fantasy VIII
4. Final Fantasy IX
5. Final Fantasy VII
6. Paper Mario
7. Suikoden II
8. Wild Arms 2
9. The Legend of Dragoon
I started losing interest in more pure JRPGs starting here.
PS2 Era:
1. Final Fantasy X
2. Star Ocean 3
3. Phantom Brave
4. Mother 3
5. Paper Mario: The Thousand Year Door
6. Final Fantasy X-2
7. Final Fantasy Tactics Advance
8. Fire Emblem
9. La Pucelle Tactics
10. Golden Sun
By this point I had almost lost all interest in JRPGs. I have not played a single JRPG of the last 2 gens... plenty of Western RPGs which may be my favorite genre, but not JRPGs. After FFX I lost interest in Final Fantasy, which was once potentially my favorite series (as may be told by it's frequency on the list). Other than Pokemon, which I have played every entry into, the last time I think I played a true JRPG to completion was Dragon Quest IX creeping up on a decade ago.
