Plenty of people you can add on this list.

Shadow of the Colossus dynamic theme.

Mine just happened out of the blue - no symptoms that it was going to happen, just switched itself off whilst I was browsing photos then wouldn't restart.

Wipeout HD / Fury

Honourable mentions to Valkyria Chronicles and GT5

The menus are terrible. It took me so long to work out how to listen to my own music.

Once you get to the driving the game is fantastic.

Wipeout HD On Elite at Phantom speeds it's soul-crushingly difficult.

Valkyria Chronicles, when Rosie named her baby it bought a tear to my eye...

...and Portal 2 for the sheer lunacy!

I doubt that they will, but it doesn't bother me if they don't - I always use the behind-the-car cam and my attention tends to be at the next apex, not at my car.
