Treyarch redeemed themselves to me.
Graphics-I'll start off with the pros. There are high levels of detail in the troops, with excellent lighting and lots of wrinkles. They also move and animate very nicely. There will be the occasional jolty movement here and there, but overall, they are very nice. The environments are exceptional too. The buildings are spectacular from just about every angle. When you get up close, they are a little muddy, but not that bad. The ground is pretty nice, but far away, it gets a little muddled. The trees are exceptional. They even sway in the wind and everything. The grass is very nice too. There are individual strands of grass that move in the wind. This game has some of the best lighting around. Smoke is very nice, but it is 2D. Haze looks real and they way light penetrates in places is unbelievable. The ambiance in this game is just incredible. Also, the focus blur when you aim looks really nice and it works really well. Now for the cons. On the PS3 version at least, there is some slowdown. It isn't as bad as some people make it out to be, but it is noticable. Also, the ragdoll is nice but it isn't perfect. The bodies will have lots of glitches and sometimes just hang in the air. There are also some glitches in the levels where you will fall through the floor or get stuck on the wall. So far it has happened 3 times to me. Overall the graphics are nice and very good looking but the lack of polish is evident. Most things just look incredible, but the graphics aren't without flaws.
Sound-WWII games always have good sound. Atleast most of them. This one is no different. The guns and explosions are some of the best in the genre. They're that good. Voicework is also nice, but nothing too special. The music is well orchestrated and is top notch. The only problems I have with the sound is that some of the small things like menu sounds are kind of muffled and when the battles get really intense, sometimes things that should make sound, don't. It's rare but I do notice sometimes in the heat of battle, my gun won't make a reload sound.
Value-The campaign is a pretty good length with a few unlockables and varied difficulties. Also, there are several paths to go through on each of the levels, so the single-player alone will keep you busy. When you put the multiplayer into the mix, you get a very long lasting game. This is worth a buy definately and not just for now. Some things that hurt the value though are that there is absolutely NO stat-tracking or ranking in online. Also, there aren't any motives to play the campaign more than once. Call of Duty 3 has it's problems, but it is a really fun and authentic WWII experience; probably the best one to date, I might add. Some aspects are better than COD2 and some are worse, but overall, I'd say its an upgrade. The most relieving part is that this is made by Treyarch and it is very good. Can't wait till COD4.
