Xenoblade Chronicles, many claim it is the greatest JRPG this generation outside of those on handhelds. One can choose between Japanese and English voices, which is a bonus I wish was included more often. I didn't have too much hope of a localisation, but now it is confirmed I am over the moon. After Zelda SS, it is easily my most hyped game.

I also think there isn't nearly enough Megaman Legends 3 hype, especially considering how long fans have been whining for a new game in the franchise

Asura's Wrath - GOTY 2012 potential
Hawken - looks incredible
Dark Souls - increidble difficulty, sign me up
El Shaddai - variety of gameplay they described sounds like a breath of fresh air

for games that are actually under-hyped on vgchartz at least
Professor Layton vs Phoenix Wright- combines my second and third favorite ds games.
Dota 2- mainly because Hon's been down more than its been working lately.
those are the most underhyped for me.
There are plenty of other great looking games, but imo they get plenty of hype such as dark souls, xenoblade, the last guardian, etc.

Resistance 3, Amy, No More Heroes Paradise and the next Silent Hill

Gravity PSV
Twisted Metal
Starhawk

If it ever comes out, I reeeaaally want to play Edge of Twilight. Having said that, its future is looking a little too grim to say outright that it's even coming out. :/ Still, I really want to play it!
Another one I'm looking forward to quite a bit is Kingdoms of Amalur: Reckoning. Anything penned by R.A. Salvatore has to be at least decent, right? Also, I'm digging the art style quite a bit, and the official trailer for E3 was a pretty great watch. So, my two biggest right there (that are under-hyped, anyway).

I don't know how the game that walked away with ''Game of E3'' award from most sites qualifies as under-hyped. Your not the only one to do this however, which kinda begs the question what the point of the thread is. I mean, the OP mentions Dark Souls which has tons of hype surrounding it.

EDIT: And...''One of my favorite new IPs.'' I guess under-hyped and new IP have radically different meanings in different parts of the world.

lmao, but really dark souls is a game I CANNOT wait for. I can't wait to get the damn thing already, the crazy challenge is great! Though hard, demon's souls was still a very fair game, which is one of the reasons why I liked it so much.

Yeah agreed:

Bioshock:Infinite is NOT a new IP and is NOT under-hyped. Not at all.
