Do you mean the level design of Bad Company 1 or the story in Bad Company 1?  What I saw was open-ended would be maybe the hunting of gold down, and the level layout.  As far as I can tell, the story was linear.  I would say also the story was a decent change from the norm, reminding me of M*A*S*H a bit, unlike the sequel.

I think CoD is good at what they do.

But what games like Battlefield do is infinately more fun than what games like CoD does.

And Counter Strike does what CoD does but better.

The reason why I "hate on "COD is because Activision is the publisher and because the franchise is a yearly rehash thing!

Yeah, it was the level design. The fact that the story doesn't change isn't a problem, since it's a straight up "get the gold!" story, though that and the characters was it's charm, definitely. Going back to the levels, sure some parts were linear, but a great deal of the game was open ended, as in had multiple paths. The 2 most memorable ones for me are the secret passage that leads behind the castle and troops in the level where you have to rescue your friends, and when you have to get to the port through a huge field, just blitzed past in a light vehicle, it was so fun.

I remember successfully completing a number of levels in the first by going around the edge of the map and sneaking by everything.  For me, the story in the first was better, and I was hoping the second would have them as mercenaries battling the other mecenaries.  But, NOPE, they ended up toning down the humor a lot, and had a storyline like MW2.  It was SO disappointing to me.  I didn't laugh as much in the second one's single player.  I feel Bad Company does a MUCh better job as a series when it tries to lampoon other FPS titles.  B-Company in no way, shape or form are supposed to be hardcore spec-ops guys.  I want to know what happened that got them back into the military, considering the ending of the first.

i could not agree more

I dont like CoD because its gameplay hasnt changed since CoD2.

i didnt really like COD type games pre 08

i think there ok the SP does offer lots of gunplay type gameplay and is action packed through out i didnt relies this when i was haten on em and the new stuff that has been added like zombies, horde mode, and spec ops really adds to the SP for me

but its starting to feel dated and not the graphics or anything but the lack of animations go look at KZ cryisis and now BF3 trailer look at BF3 where the player jumps over the ledge you cans see his arms move accordingly, and when hes nearly blown up by the car bomb, also the to different prone animations the one in the duck is different to accommodate lack of room then the one on the roof 

COD feels like them old FPS PC games of the 90s just a arm holding a gun floating in mid air

other than the lack of player animations i dont really have much hate for em

I find COD extreamly enjoyable but, what kills the COD experiance for me is all the kids swearing, talking about their 14 year old love life, the singing, camping, spawn killing, and yearly release of a new game. I will never go back cause Once you go counter strike source theres no going back.
