Heres what im thinking...

GTA 1 - GTA London was PC games that did okay in popularity, but as GTA3 launched the GTA franchise really blew up the gaming industry with its in your face attitude where you killed cops and had sex with prostitutes. The game was on everyones lips and it helped define the PS2. SONY later on released the license of exclusivity and said that they felt the Playstation brand, as well as GTA and Rockstar, had enjoyed the cooperation but that it was time for some other franchise to help define the console.

Along comes Uncharted 1, gets good numbers and creates some buzz with its cinematic touch. It gets a solid fanbase and ND/SONY decides to do Uncharted 2. A game that has cause a hugh buzz around the gaming industry, and graphics wise aswell as storytelling, really hits mainstream and people all over wants to get their hands on it. Much like GTA3.

Could Uncharted be the new GTA in terms of really help define the PS3 and the Playstation brand? Aswell as help sell hardware and become a solid big seller? What do you think?

Or... maybe even a new MGS. The same love for the main character is present in both Uncharted and MGS. Both have great storytelling and stealth/action that really works. DISCUSS!

Doubt it.

But, if they stop the continuous story and continue to keep the quality up, who knows.

it can easily be the next metal gear for the sony brand. honestly even though i played GTA a lot i never thought of it as defining the playstation experience and the series now garners next to no interest from most people i know including me.

No..we have question how long UC will live as a franchise, SONY known for using a new patch IP's per gen. If UC does live its gonna need a waaaaaaay mega caimpaigne

In a word, nope.

Uncharted is doing great, but I don't see it becoming a staple for the masses.

No, nowhere near as huge

Uncharted will never catch up to MGS in terms of quality and popularity but still it will be defined as one of the must haves for PS3.

MGS >>>> Everything else.

I absolutely think it can be... if the franchise keeps innovating and pushing the limits of the console, it'll be the must own franchise for the PS3.  Personally, I'm not a huge MGS or GTA fan, so to me Uncharted already is my favorite franchise.

no please do not expect it to

it will sell less than a third of what GTA 3 sold

The game you are looking for may be The Agent

but its too late for a GTA type killer app to come now anyway

the GTA of this gen was the Wii franchise

BESIDES

MGS4 >>>>>>> ALL as sabby said!

I think it could be as big as like Crash bandicoot was
