Right on bro. Off the top of my head

I think Shenmue should be revamped. - It was too aggressive for its time and would cost a lot less these days. Plus it would be hard to get some people into the whole saga starting off on a newly fresh looking third installment.

Jet Set Radio - The original was better than the follow up, although the follow up was quite good too. I think the first games controls would be a shoe in for the Wiimote: Imagine graffiti tagging by having to move your Wiimote in certain patterns.

REZ - This game is an experience that just we just need more of.

Skies of Arcadia - We need another sequel to this great RPG! This was equal to how great FF's use to be.

Grandia - This is one title that I think started to slip way off course. This one fits the original question well, and really could help itself out by getting back to the Grandia II formula.

Chu Chu Rocket - A fantastic puzzle game that would do well in this feverish "casual" climate these days.

Marvel Vs. Capcom - Capcom lost their rights with Marvel, so this one just died at its peak. I wish Capcom would be savvy enough to at least try and see if Marvel would let them do a DC vs. Capcom version.

River City Ransom - Is it just me or do the characters designs from EA's My Sims scream for a 3D remake of this classic?

Road Rash - This one would do really well I think these days. Online would own and the new power of todays consoles could make this incredibly graphic and hilarious.

Eternal Champions - With all the cries for blood from the gaming community, I'm really surprised this one hasn't been revamped for a 3D uprising. If done right, this one could easily out do MK these days.

That's all I can think of at the moment. Not too hard to see I'm a bit of a SEGA fanboy. Thing is, Nintendo and many other companies have continued to evolve and keep many of their staple franchises fresh and innovative for my tastes. Oddly enough mainly SEGA appears to have let a great many of its quality franchises die off.

Let me fix Final Fantasy.
First thing the protagonist is straight, not the pretty boy type. He has facial hair and dress clothes fit for normal people (no more cosplay like outfits). The girls do not need to use those revealing clothes that make them look like strippers (Fran, Ashe and Rikku on FFX-2).
All the characters have a background and there is a lot of character development during the story. All characters have distinct skills, the black mage cannot learn curaga or attack with a bastard sword.
The Summons are simply called "summons". That Aeon, Eidolon, Guardian Force, Esper bullshit is over.
There is no need for a new "(put any gimmick here) system". Magic and skills work like they should, you just learn it. No more sphere and license grids, junctions or whatever.
That is it.

Elebits Gone Wild (Think elebits meets pokemon snap. oh snap)

Looney Toons v. Mickey and Friends

BOOM! Madden '09: Tinactin Edition for DS, like Trauma Center, BOOM!

Animal Conflict, what happens when animals cross paths.

Sim Ancient Indigenous Peoples

Elder Scrolls Horse Racing: With real online betting.

Super Smash Extreme Beach Volley Ball

I could go on all day.

 but just calling them summons is kinda lame and traditional... Aeon sounds cool. "I just summoned my summon" sounds like crap but "I just summoned my Aeon" sounds awesome.

Amen, It's a Mii. Final Fantasy either needs to drop the androgeny or just make it about a girl if that's the way they want to draw. Although I'm kinda heading into the direction of NO MORE FINAL FANTASIES! Put that R&D and money (read....billions) into some other franchises. How about a REAL Secret of Mana....a Chrono Trigger....Secret of Evermore. Please, please please.

Steven...I'm not sure exactly what Elebits do when thet've gone wild...And the looney tunes vs. Disney would be classic.

Thanks to everyone for keeping this thread rolling.

what do you mean that game was sweet!

Bring back this franchise: Golden Sun. One of the best RPGs I've ever played =]

Pokemon may still sell like Crack, but it needs a Fix. That fix? The Pokemon MMORPG. I really can't think of a better series for that type of game (including existing MMORPG's). This game could actually have a point! Trying to catch them all! And after so many games, there would be hundreds! of Pokemon to catch. Join tournaments, Train Pokemon, Catch new ones in the jungle, storm Feral Pokemon infested ruins (that's your dungeons!), and generally just explore. Nintendo is sitting on the potential for millions with this one.

A MARIO FPS
MARIO PAINT BALL

I would love that game.
