DC was a joke....much more for C-S players than BF2 players. Chopper took more skill to fly than in BF1942, but the physics were dumbed down drastically to make it more comfortable for those with no ability to correctly gauge the arc and direction of a tank cannon when moving and firing at a moving target. In DC, you just put it in the cross hairs. I took out three tanks at the same time in the open desert on a BF1942 map once in an epic 5 minute battle....fwiw I was promptly dive bombed by a German plane a second after finishing off the third in a beautifully poetic conclusion.
That said, BF2 IS too much like DC for my taste, but I still like it better.
