It looks amazing, from the stealth system to the action, the fact that you can play the entire game in FPS is also a pretty significant change.
The grahpics look nice as well, This is the ONLY game i want on the PS3.
The only criticisms I have is how Snake uses his sniper rifle that is very loud but none of the other PMC's are alerted! I hope that will be fixed by release, Also i think its very unrealistic how rolling over two guys in a barrell can kill them, thats just silly. Apart from that, so far I have no complaints about this game. (Oh, that and it being PS3 exclusive)
I think that this game allows alot of freedom, I'm not sure but i think in alot of sections your given a huge city area and you can approach the situation however you please from any direction, like a sandbox game.(GTA,Oblivion, etc)
If it doesn't pull any surprises on us like the bizarre and confusing storyline in MGS2 or having to play as a little sissie then that would be great. if it has the great boss fights and engrossing characters of the first or third game then this is set to be one of the best games of 2008 already.
Can't wait.
Edit: Ok, I have more criticism, ok, I also don't like how snake controls that little robot in the middle of the street twiddling his thumbs and he doesn't even get shot! WTF! so much for stealth.
I also don't like just after that part, snake gets shot fom behind, he turns around and shoots a guy then another guy behind him, they get shot, stand still and then jump off the roof :laughing: in true stormtrooper delayed reaction death. Unimpressive AI reactions.
My final criticism is how when he gets to the end of the street, and clears the place out he gets shot again from a roof. He stops in the middle of the street, in easy view of getting shot, loads the RPG which takes several seconds, then stands full view of the snipers taking about 5 more seconds and doesn't get shot or killed!
Anyway, apart from that, it looked really good, I guess what I've just talked about might be bugs and need to be ironed out. MGS games are generally pretty smooth and clean, so I have some faith in those problems being fixed.
