This was the very first game I bought for my PS2, costing an outrageous 70 dollars, it's a good thing they don't cost that much anymore. Is it just me or was Call of Duty games fairly enjoyable on the PS2, they may of not been the greatest, but they had a certain charm to them.
The PS2: The game-play was much better than previous entries on the system. The game goes by much faster than the PC counterparts, and get's completely ridiculous with nonstop explosions and gun fights, this would latter become the standard format for the series. You get the regular WW2 guns that you know and love, the only new gun would be the trench gun, but you barely get to use it. The close courter battles were a nice edition, the best one is when you fight an enemy solider with a knife and grenade. There was a mission where you have to drive to your checkpoints, there is a few mini games where you have to set up some explosive charges, a little more variety here. The game is pretty good, but this feels less realistic, and more for young kids that could care less for what happened during WW2 and more about nonstop action.
The PS3: Since I only had it for a short time, this is going to be brief. It's just a better looking and more enhanced version of the game. There was one notable problem, the game glitched out at the start of a mission and you could walk beyond the boundaries and invisible walls, thats the first time I have ever got out of the map in CoD single player.
I have grown to like this game as time passes, it reminds me of a simpler time during the series, back when I used to care for the single player campaign. Check it out if you are interested.
