Halfway through gameplay (Drake just got a gun).
Love the use of the climbing peg, really cool. Also using vegetation as cover = awesome.
Drake's banter with himself is, as ever, excellent.
The graphics need work, but its Naughty Dog, I am sure they'll have it ship shape by launch.
I'll second what others have said about the climbing though - its just getting more and more outlandish and hard to believe what is such a core element of the game.
starcraft - Playing Games = FUN, Talking about Games = SERIOUS
