Way back in 2004 I bought this game for the gamecube. I played it for around 20 minutes and as a younger dumber version of myself, I wrote it off as a "kiddie" game. I returned it to Gamestop. Fast forward to 2011 and I see that it's on sale for 800MSP. I buy and play longer than 20 minutes. When I was done, I realized how stupid I was in 2004. This was easily one of the top 5 best games I have ever played. The mix of platforming, stealth, collecting, and story were amazing to me. I'm glad you bought it, I hope you enjoyed it as much as I did. And I've read rumors that a sequel is supposedly in the works, but those are just rumors.
I have come here to chew bubble gum and kick ass. And I'm all out of bubble gum.
