Which is better infamous or battlefield bad company

I'm going to assume you mean Bad Company 2. Then I'll say that they are very different. BC2 (Bad Company 2) is a first-person shooter while inFamous is...a third person shooter I would say, but you are firing lightning rather than bullets. BC2 is rated "M" by the ESRB; iF is rated "T". inFamous has about 20 hour game, but no multiplayer. (In my opinion, adding that that would ruin the game). BC2 is only 8 hours or so, but it has multiplayer. The multiplayer is just as good/better than Modern Warfare 2, but has less modes. Personally, I like inFamous better.
