why can't they slow it down with bigger levels and make it so that its actually slow paced house to house fighting like it would have been?
Because once you die in real life there is no 10 second timer until you come back. There is no possible way to ever, ever, EVER reinact a war through a console/comp game *realisticly*
And those house to house battles could have taken hours. The average HL player wants action action action. you'd lose intrest easily if it were slow and big levels where it takes 10 minutes to finally get into a goddamn firefight only to be shot in the head as soon as you arrive on the scene. Not even I see that as an idea of *Fun* which is as noticed by all why BF1942 was never taken seriously. TKing became more fun then playing the actual game correctly. Unless you enjoyed walking 5 miles to the nearest enemy.
