HA! I actually got in on that deal. But that was before I was a registered CAG (and stupidly only checked the main page). Unfortunately, the platforming in the game is not incredible, and the whole notion of seamless transitions between multiple gameplay types fails on both a techinical and game design level. Both Ratchet and Jak run circles around this game in the gameplay department, and can each be regularly had at under $10.
I ended up trading in Haven in a trade-in special (back to EB games) for $4.50.
