Probably Dewprism (aka. Threads of Fate). It's a barely-heard-of Squaresoft game released back in 2000 for PS1, and it fell beneath most peoples' radars since it wasn't a mainstay Squaresoft RPG or even that big of a game time-wise. In an age when games were touting 100+ hours, Dewprism dared to be a 15-hour RPG.

And it's all the better for that short play-time, too. The characters develop just far enough for you to care about them, but don't overstay their welcome like so many video game characters do. The gameplay is also fairly innovative, with two separate play styles and a rather unique stat-boosting system that works swimmingly well. Said system makes New Game + mode a blast, too. It may not be the biggest RPG on the PS1, but it's definitely one of the most fun.

NMH-NO MORE HEROES

not sure if it counts but yeah its that or the world ends with you than eternal darkness.

 i got that on gamecube it was the bets thing ever, a sequel is veyr much needed

Thanks for reminding me about PSU >_> I was addicted to that...

GRANDIA.

I was going to say this.  The game was so sick, I would die for a sequel.

Definitely Shenmue 1&2. I'm still hoping for a 3rd title.

Lufia I/II and Disgaea

Okami is definitely a worthwhile mention here...I think a lot of people don't know what they're missing out on.

It's at the top of my list!  I swear!  I'll get it soon!
