My nomination is Midnight Club: LA (10 HD videos available at the link)

It's a superior use of Rockstars RAGE engine to GTA IV (seriously, if GTA ICV looked or was as polished as MCLA if would be a far far better game than it already is) and didn't get anywhere near the amount of publicity or marketing focus as it should have done. It's better than any of the NFS games, better than any of the Burnout games, and it looks better than PGR4. If you like racing games, you'd be doiung yourself a great dis-service by ignoring it.

But Midnight Club aside, which other games this gen haven't garnered the kind of attention they deserve?
