Damn, I guess you have never played a game that you have been impressed with the AI (unless you count the times you first started gaming). I think you will always be unimpressed with the AI in games. I'm glad I haven't gotten to that point. That's a lot of missed out joy from games.
Its not like i havent played games with good AI, not that at all, i have played quite a few games with good AI, Metal Gear Solid 4 is just not one of them.
The whole game is based around scripted sequences, scripted walking paths for the AI and respawning, the only thing the AI are good at is running towards the place where alarms go off. In firefights the AI is decent at best (they manage to come towards you, but they dont know how to flank you or take cover effectively), they are very stationary once they found you and you got all the time in the world to kill them if you want to.
If you get the AI to look after you, they aren't exactly very good. They will walk over to whatever spot you got spotted in, stand there and look about for a few seconds, and walk off. Its completely unrealistic and stupid. If i just saw some ninja runing around, im gonna do more than just look around for 10 seconds and stop caring.
I played games in 2005 with vastly better AI than this (F.E.A.R.). I'm sorry, but there is nothing special or particularly good with the AI in MGS4 (and no, turning on the hardest setting didn't really make a difference).
There are so many things that feel dated with Metal Gear Solid 4, the blocked off pathways, the absence of jumping, the limited movement possiblities, and the AI.
I think most of this comes from me never really playing a MGS game before,maybe experienced MGS players are familiar with the limitations of a MGS game. Im not, and most of the similar games i have played the last couple years are far more open and have far more movement possibilities.
Im not used to not being able to climb up 2 boxes stacked on top of eachother, or a bar table. I have done this in games for years,, i have also played games with AI on par or better with MGS4 for years. The game feels like a PS2 game with really really really really good graphics (im not saying the graphics are bad, the gameplay just makes me feel like im playing a PS2 game)
Dont get me wrong, i enjoy the game and the cutscenes (althought some could have been a bit shorter, atleast i kinda "get" the whole point of the cutscene and sometimes they keep talking slowly and long around the topic that ive allready understood), i enjoy the humor, but its certainly not the technical marble that so many people here wanted it to be.
MGS4 looks good, sometimes very good, but other than that MGS4 doesn't do anything thats hasn't allready been done better in some other game.
Some things with MGS4 are just wierd to me. I dont get why all the scenes in this game are so small (and we gotta load so often) aspecially not considering that we got to INSTALL the game SEVERAL times (thats right, you gotta RE-INSTALL the game after each act (!!!), it only takes 3 minutes or so thought instead of the initial 8).
The visual fidelity just isn't there for me to understand why all the areas are tiny, and we gotta load so much, even with repeated installs.
