Overall, if one is an online game addict with nothing else to do this may be a really great game.
-great sound (as in battle sounds; music ... well, nothing to brag about)
-decent graphics (better than in BF 2)
Negative:
-preinstalled adware (I won't call it spyware, but it's close)
-crippled singleplayer (5 maps for $50)
-a huge unlocking system that benefits people who don't have anything else to do but play this game in multiplayer mode for hours (why are weapons locked and can't be unlocked in singleplayer since it doesn't affect more competitive online multiplayer experience)
Other (mildly negative):
-weapons and vehicles are good, but they seem to be a few decades away from reality not 150 years
-knife? ... wtf ... 150 years from know, a knife just doesn't belong. What's the unlockable upgrade kit for knife -- five medium size rocks and a baseball bat? Which brings another point ... "dog tags" -- lol, make it a chip implant more likely
-weapons reloading time, recoil, accuracy, etc ...not much improvement since AK-47
-game loads/reloads as slow as BF2
Gameplay: 1 for singleplayer; 7 for multiplayer - overall: 4. Not all of us have the time or desire to spend hours playing this game with total strangers. Sad thing is that the longer the game stays as a popular online multiplayer the more it gets populated by a$$holes & cheaters -- it becomes a waste of time for others who just want to have fun.
Graphics: 8.5 -- to me they look better than BF 2.
Sound: 9.5 -- great sound.
Value: 1 for singleplayer; 5 for multiplayer - overall: 3. $50 is lots of money for, basically, a BF 2 mod. And if that wasn't enough, EA decided to supplement their bottom line with in-game ads (a very bad move).
Tilt: 2 -- mostly because in-game ads. It does change the impression of the company who does that. ... and a stupid suggestion (to paraphrase EA): if you are bothered by it don't connect to the internet ... but you need to connect to the internet to play the game. Doesn't make much sense.
Overall, if one is an online game addict with nothing else to do this may be a really great game. Otherwise, for others there is a certain amount of fun like in other BF2 titles but don't expect too much from it. If you are still curious ... download a demo, play the game at your friend's, or wait until its price comes down. Definitively not worth $50 .. or $49.95 to be more precise.
