A near perfect game that suffers a bad save system and is far far to short.
But it's far too short. I like to take my time playing a game. I like to explore and see whats around the corners that are not a part of the main story line. Sadly COD4 often doesn't let you do this. Many of the missions are time limited or have a strong enough illusion of being time limited that you don't feel free to explore the environment.
Thats a sad thing because the environment is beautiful and it just begs to be explored. Normally there is an easy way around this. You just save and then go off exploring. Then you restore with no "time penalty" or loss.
That brings me to the other negative of the game. COD4 uses the notoriously console centric and gamers unfriendly method of check point saving. THERE IS NOT REASON FOR CHECK POINT SAVING TO BE THE ONLY METHOD OF SAVING. Hello?! There's no reason to do it on a console anymore, so why WHY W*H*Y would you do this on a PC? Thats a big let down.
COD4 is in all other ways a great game, and it's worth playing. But if you're a single player person and you don't care about multiplayer, find it used. It's too short otherwise.
-1 For check point saves
-1 For exceedingly short game play
Time to complete game: about 8 hours.
ps. When you're done, watch the credits.
