Finished Bentley's Hackpack! There's an end credits sequence you trigger by getting 311 tokens and getting the arcade key prize. Use the arcade key in the locked arcade machine to see the Sly characters rocking out!
You get the game's only gold trophy for doing this, and in pursuit of it you should acquire most of the other trophies as well. It was a fun challenge. The motion controlled stages weren't so bad once you accustom yourself to them. $3 well spent.
I started playing Sly Cooper: TiT. It's a lot fun so far. Very faithful to the previous games with some welcome additions. More thoughts later.
