A great game that is fun in every definition of the Word
People say that the graphics are dated, but it still looks quite nice. Sure it isn't the caliber of Far Cry, Half life 2, or FEAR, but the weapon effects, the huge levels, grenade effects, and particles are all very well done. The death animations are a pretty good in my opinion (except when they fall off rails; crazy) because they are the type of death animations we want to see. the engine is also capable of putting a huge number of people on screen fighting eachother. On the russian campaign I saw at least 50 russians getting ripped apart with MG42's. It's a sight to behold.
Sound is one of the best aspects of this game. Many people say the music is the best about this game but I disagree. The music, while nice, is often muted my heavy gunfire. However, there is nothing wrong with that since Call of duty has some of the best sounding weapons and reload sounds.
The value is pretty good too. The campaign in word sounds short, but it's more like Max payne in that you'll feel like you've experienced quite alot. Don't be afraid to get this game because of its length. Also the multiplayer is whole lot of fun.
Overall Call of duty was just another great experience for me. If you love great weapon sounds and animations and pitched battles with 50 people on screen shooting eachother this is your game.
