I'm kind of on the fence with purchasing this game on Steam.  It was on sale for 33% off its normal price ($49.99) a few weeks ago, and I didn't bite.  Now I am interested and don't know if it is really worth the $50 price tag.  I put this in the wonderful, caring hands of the GiantBomb community. 
 
Did you like it?  If so, what did you like about it? Do the guns feel better than Modern Warfare? How is the multiplayer?  Basically, is it worth me buying it NOW, or waiting until there is another sale?

Wait until another sale. I personally regret paying full price for it.

Oh wow thank you - I have guys over in the Bad Company 2 board saying it is awesome.  I will keep your opinion in mind.

MW2 is a broken,frustrating and unbalanced mess. 
BC2 is a worthy purchase all the way.

I bought it on sale and would pay full price for it. I have put like forty hours into it. It is a completely different than MW save for shooting dudes. 

Love it, but any single experience depends on the team you're playing on. I'm an objective-minded person, so if my whole team also goes for the objective we're golden, we finish maps in 10 mins (and I usually finish first or second on the scoreboard). On the other hand if your team is a bunch of KDR minded retards that stay back and snipe so they can get a 4:1 score for the game but also totally lose, then you're going to have a rotten time, continuously getting killed due to no support from your team, and losing due to not being able to complete the objective. Basically, it's not like MW2 that if you're good then you score a lot kills and have a good time. The maps are so huge that even if you're really good there can easily be 3 people staring you down at a scope at the moment, and with no support from your team you're screwed. But when everyone is working together to secure a victory, and when you're covered by your teammates in multiple ways while you cover others or storm through with a vehicle, it's an experience all to its own. 

Single player sort of sucks, it's like a cheap call of duty knock off without any of the talent infinity ward has. Multiplayer is fun though and the complete opposite. It's actually better than modern warfare 2's multiplayer.

Well they are referring to the online multiplayer. But the story of the campaign will highly depend on your story preference given the fact that the campaign's story is actually a prequel to the events in the multiplayer. :D
