We get it.
Morrowind was great.
So was KotOR.
And, from what I've heard - Jade Empire's good & Fable's a love it or hate it kind of game.
That's about it, though.
When it comes to Xbox RPG's - that's about it.
Off of the top of my head, PS2 also had:
Dark Cloud,
Dark (Chronicle) Cloud 2,
Baldur's Gate: Dark Alliance 1 and 2,
Steambot Chronicles,
Ephemeral Fantasia,
both Raido Kuzonoa Devil Summoner games,
Baroque,
Dawn of Mana,
Front Mission 4,
Gladius,
Grandia Xtreme,
2 or 3 Growlanser games,
King's Field,
Magna Carta,
Okage: Shadow King,
Rogue Galaxy,
at least 3 different 'Shining' games,
2 Summoner games,
Tales of the Abyss & Legendia,
Legend of Legaia,
Bard's Tale,
LotR 3rd Age,
Valkyrie Profile: Silmeria,
2(?) Phantasy Star games, and
Odin Sphere...
off of the top of my head, for some ARPG's.
No, most of your list weren't exclusives -
and...
No.
Xbox wouldn't have been the go-to console (even for the ARPG's that you keep bringing up) for RPG's of any variety.
It would have, however - been the go-to console for RPG fans who wanted to play the 3 or 4 Big/very good & well received ARPG's, that the PS2 didn't get
IMO
I stand corrected on the amount of PS2 action-RPGs, I didn't even know about some of those. I simply don't do strategy games, so I completely left those out. I did the same with strategy games on the XBox side of things too, though.
But I'm not gonna concede on the quality of the action-RPGs on XBox, especially to someone that says they only "heard" about which ones were good or not.
Let me point out some good XBox exclusive RPGs since you think only 3 exist worth playing:
-Arx Fatalis - If you like Ultima: Underworld, you'll love this modern-update of that gameplay.
-Blackstone & Magic - Another Diablo clone, but I love those.
-Dungeons & Dragons: Heroes - Hack-n-slash RPG in the vein of Baldur's Gate: Dark Alliance. Very addicting.
-Fable - When the game came out, it was one of the most ambitious games ever made. The world is highly-detailed and interactive. There's so much to do to keep you busy. And you can get very unique and personal in how your character looks and acts. I'm not sure where the "love it or hate it" is coming from. Obviously not EVERYONE is gonna like any single game. But I'd think scores in the 9s means it was generally well-received by most people.
-Jade Empire - Quite unique in it's setting and gameplay. Focuses on Feudal China as well as martial arts and mystical arts. It has a great morality system, too.
-Morrowind - Best RPG of that generation, bar-none, IMO. I put hour upon hours upon hours into that game, and there was still plenty of unexplored regions.
-Phantasy Star Online Episode 1 & 2 - Not exclusive, but also not on PS2.
-Shin Megami Tensei Nine - I haven't played this, to tell the truth. But I've heard some fanatic fans of this series.
-Star Wars: KOTOR 1 & 2 - I think we all know about this awesome RPG series. Bioware is awesome.
-Sudeki - An overlooked gem of an action-RPG with a complex battle-system and very soft and pleasing graphics.
And since you seem so hung on exclusives and all, you realize you're list has games also on XBox, too, right?
-Baldur's Gate: Dark Alliance 1 & 2
-Bard's Tale
-Gladius
-Lord of the Rings: The Third Age
In the end, I think we both come from two completely different tastes in RPGs. You seem to enjoy Japanese-style RPGs and strategy-RPGs. I seem to gear towards hack-n-slash and action-RPGs like Baldur's Gate, Elder Scrolls, and King's Field type games.
But the fact still stands that there's plenty of great action-RPGs on XBox. It is NOT crap for RPGs, unless you are the type looking for JRPGs. A Western-RPG is still an RPG.
