Although, I would give Battlefield an 8.5 or 8.0 for the single player...
lol
95% of all fps games these days dont deserve more then a 5/10 for the singleplayer, not played the single player for BF3 yet and never will because I know exactly what its like. So many "casual" people buy games based on reviews and hype and dont really know what they get, and alot of them dont play multiplayer so they get screwed over by games like these.
That doesn't make sense. How can someone base a game on reviews and not know what to expect? If yout read unbiased reviews, you should know what the game focuses on. True, most single player campaigns in FPS's are junk compared to the multiplayer... But Battlefield 3 doesn't NEED a single player to make the game great. For example, if BF3 shipped without a singleplayer/co-op, and maybe 3-4 more maps, would the game rating change? I bet it would because reviewers would then butthurt over the lack of solo operations, thinking it will alienate people from buying the game.
PULEASE!

If DICE went multiplayer only (like everything up to Bad Company), the game would have been just as fun. Personally speaking, the story is thin... But the set pieces are great and it's more of a tutorial for infantry combat in the multiplayer.
