I beat the game in 1P scenario mode yesterday.
As is pretty obvious, it isn't great. There are lots of flaws and issues with it.
However, it is playable, and is by no means a terrible game.
I was going to write up a review, but I can't be bothered.
I did want to say this though. While in fact the script really is truly bad, and quite a few of the voice actors get it wrong too (the guy that does Shane included), the one person that got it right was the voice of Duval. Yes, this guys deserves some credit, because despite the fact he has to act out some of the worst dialogue ever written, given the context of his character (as you know it after having beaten the game) he actually does a very good job of it, and is probably the only VA in the game that gets it right. Ultimately, he is believable as Duval, and pretty much everyone else in the game isn't belivable in their roles.
Anyway, my score for the 1P game offline would be a 6 or 6.5 out of 10.
I'm going to mess around with the online game between now and MGS4, when this game gets traded.
