I'm now at the final boss (I'm guessing) of the game and he's by far harder than any other "boss" you've had to fight thus far. They really ratchet (pun intended) the difficulty up on him - gave up in frustration last night.
However, I adore this game. I didn't even finish the last R&C on PS2 because I just got bored with it - felt like one too many retreads - but something about this one feels fresh and fun. Sure, it's probably a combination of the visuals and everything, but it just felt like a wild romp and I never felt like any one level or task lasted too long and because belabored.
The game is absolutely gorgeous. I got this and Uncharted both for Christmas and I honestly think I prefer R&C's visuals because they're so rich and vibrant and there is sometimes just so much madness going on on screen that I'm awe-struck.
Anyway, really can't wait for another one. I love the style of the game, it really makes me wish Naughty Dog were working on a Jak & Dakster game for the PS3 - this style looks really cool when done properly this gen.
