[FUBLU]

Just had another thought...
I would like to see an open world game with the option of having 4 Avengers (out of SEVERAL to choose from) take on different MARVEL enemies. There could be like a map of the world and you could choose to take on different missions as the game progresses.
One could remain in New York and stop on Norman Osborn's plans from making the Dark Avengers the toast of the town.

Travel to silicon valley to aide Dr. Pym and face Ultron and his make shift "Skynet" before it grows into a massive problem.

Take a Quinjet to Las Vegas to prevent Red Skull and Hydra from blowing up Caesars Palace while the President is there watching a major boxing match.

Head to Chicago to prevent A.I.M. and The Mandarin from collaborating on a deal to bring massive destruction.

Take a trip to Asia and stop "The Hand" from a major assassination.

Find a portal from Germany to Asgard and prevent Loki from trying to rule the 9 realms.

Eventually one could end up in Latveria to take on Doctor Doom only for him to enlighten you that the real threat is intergalactic and have you rush to Houston to be transported to space to take on the Kree & Skrulls to eventually have you battle with THANOS in the end!

Of course within all of this one could explore the areas and do small missions along the way.

I know something this massive would take years to prepare for and make but, I'd be willing to wait if it's done on the scale of a GTA or something of that nature.
