I would rather they do an older storlyine than one of the recent event books. Like a "days of future past"-style storyline, set mostly in the future.

I'd like to kind of create a prequel to The Avengers featuring: 
Loki accidentally having the team ban together to stop him, Hulk joining after fighting them all, The fight with Namor & the rebirth of Captain America, Baron Zemo & The Masters of Evil, The birth of Wonder Man, The invasion of Kang the Conqueror, Ultron turning evil, Graviton strikes, Hordes of HYDRA attack S.H.E.I.L.D and the Avengers stop them, Magneto attacks & the X-men join forces with the Avengers to stop him, and finally Dr Doom tries to invade America with his legions of Latverian Doombots. 
 
Playable characters (including the ones unlocked later on in the game): 
Iron Man, Thor, Ant-man, Wasp, Hulk, Captain America, Hawkeye, Hercules, Black Panther, Vision, Ms. Marvel, Falcon, Black Widow, War Machine, US Agent, Wolverine, Gambit, Storm, Cyclops, Rogue, Jean Grey, Beast, Jubilee, Professor X, Scarlet Witch & Quicksilver. 
 
 
Bosses & Other villains (sort of in order of appearance): 
Loki, Namor, Baron Zemo & The Masters of Evil (The Melter, Radioactive Man, Black Knight, Enchantress, The Executioner, Abomination & Wonder Man in a solo fight), Kang The Conqueror, Ultron, Graviton, Baron Strucker & The Red Skull, Magneto & The Brotherhood (Juggernaut, Mystique, Scarlet Witch & Quicksilver (before they join the Avengers), Toad & Mastermind), and finally Dr. Doom & his army of Doombots.

honestly, I would rather them do an original storyline than one that's already been done and that they'll screw up any way....

It would have to depend on the story they choose to revolve around. I don't want to throw in random characters that weren't part of the story. 
 
That being said, I think Secret Wars would make for a good Marvel Ultimate Alliance storyline. The roster from that story arc isn't huge either and is around the previous two games roster size, so I think its fits.

@cattlebattle: yeah, and it only lasted for like 2 levels all that build up for nothing! there should have been another level dealing with the seperation of the two factions- and it would have helped make the game longer- which would have helped too MUA3 should be original- that way, they can't do it "wrong" or "right"  it would just be whatever it is supposed to be per the per the people who wrote it 

 this story line is talked about " WAR OF THE END FOR ALL WARS "

can we add Rogue onto the roster? It would be amazing to put her in a MUA game

Everyone, every single godd*mn character Marvel has ever created ever. With an original story

The team I'm going to use will be

Aunt May

D-man

Danielle Cage

and Deadpool

SECRET WARS should be the basis, but with modern characters and stuff.

@BlackArmor: dang i was gonna call D-Man , shoot.

If Ultimate Alliance 3 comes out the only thing I want is for the developers to be given the opportunity to design original costumes for the characters.

i demand GRASSHOPPER! also skrull alternate costumes would be fun.

If I were in charge of doing one, I would not have it follow any book based stories so that the game could flow more freely, maybe even in the style of an RPG. Second, since that it is an ULTIMATE alliance, I'd see to it that no console receives characters that won't appear on other consoles. Third, more costumes for the characters you play and ultimate attacks that do more damage.

Finally, a character roster consisting of (at least)

Captain America

Iron Man

Thor

Spider-Man

Vision

Scarlet Witch

Ms. Marvel

Spider-Woman

Giant Man

Wasp (she could work.)

Wonderman

Quicksilver

Hawkeye

Black Widow

Black Panther

Captain Britain

Blue Marvel

X-23

Wolverine

Storm

Cyclops

Colossus

Nightcrawler

Gambit

Rogue

Cable

Psylocke

Ice Man

Emma Frost (even though I don't like her.)

Jean Grey/Phoenix

Some newer X-students

Some members of the Runaways

Blade

Deadpool

Ghost Rider

Punisher (why not.)

Man-Thing

Dr.Strange

Iron Fist

Misty Knight

Luke Cage

She-Hulk

Hulk

The Fantastic Four

War Machine

Daredevil

Silver Surfer

Nova

Star Lord

Rocket Raccoon

Beta Ray Bill (as a separate character, yes.)

Squirrel Girl

Moon Knight

Dark Hawk

Turbo

Elektra

Nick Fury

And...that's all I've got for right now.

Villains I'd like to include would be Dormammu, Graviton, M.O.D.O.K, Taskmaster, Red Skull, The Sinister Six, Hydra, A.I.M, Galactus (to conclude some, if not the, first game's story), Loki, Super-Skrull, Absorbing Man, Norman Osborn, and Shuma-Gorath.

I'd like for some lesser known or underused (as far as video games are concerned) characters to get some exposure.

Off the top of my head:

• Shang Chi
• Iron Fist
• Kaine
• Ben Grimm
• Taskmaster
• Black Panther
• Namor
• Xorn
• Fantomex
• Bucky
• Flash/Venom
