Sure, $29.99 is pretty cheap for a whole game, but do U.S. Navy Seals and Drake's Fortune actually deserve the descriptor of "Greatest?" I'd say yes on Drake's Fortune and no on Navy Seals. Navy Seals would be worth it if it came bundled with the blue-tooth headset originally included in the release of the full-price version of the game.
Which PlayStation 3 game do you think should get the "Greatest Hits" treatment next? Personally, I'd pick Heavenly Sword. I can't bring myself to pay full-price for this title, but I still want to play it. Know what I mean?
