See, e.g., Dungeon Siege 3.

Dungeon Siege 3 is dead to me -.- *turns away*

Gameplay is really nothing new, but with a good number of weapons, special attacks, powerups for both you and the monsters there's enough variety to assure you don't get bored (and it can get quite hard too). Story is the shining point IMO, but I won't say anything more ^^
Also, I'd say it's about 8-10 hours on your first run (not counting NG+), not so bad for an XBLA game.
So, I totally agree with OP. Great game.

Did dungeon siege 3 bomb really bad or something? It's like £10 in game.

I'm itching to play this. I absolutely love the old-school graphics and the cool as heck narrator. Looks pretty cool to me!

Most people don't even consider it a dungeon siege game put it that way...

DS 3 is basically a digital download title they tried to sell at full price just based off of the name. It's every bit a console/XBLA title and the PC optimization was horrible.
