The idea is to post a kind of frankenstein's monster of who you think could make an awesome JRPG.  For example,

Character and world design by Yoshitaka Amano,

The core gameplay designed and the game itself built by Level 5,

Written by the scenario writers from the Suikoden games.  Specifically Suikoden V, since they're a recent team.

That's a short one.  Feel free to go into whatever level of detail doesn't kill you.

The definitive JRPG dream team:

• Scenario made by Mistwalker.
  
  
• Core gameplay made by Game Arts.
  
  
• Music made by Mistwalker.
  
  
• Art design made by Square Enix.

Story by Hironobu Sakaguchi
Core gameplay by Tetsuya Nomura
Music by Nobuo Uematsu and/or Yasunori Mitsuda
Art design by Tetsuya Nomura

Hey, that's a good one.  Assuming we're talking LO Mistwalker, not BD Mistwalker :)

Pretty much stick Game Arts on any combat system and I'll play that game.  I also love how every random villager NPC usually has at least three different things they say in their Grandia games.
