cod5 isn't as good as cod4 in any way... i bought it when it came out and went through all the levels already almost twice by now...
it runs slower than cod4 even though sports the same gfx effects.
cod5 has horrible bugs like bluescreen crashes, not being able to go back into the game after pressing alt+tab, etc etc. in-game, most of the guns in cod5 aren't fun or useful.
it's because cod4 and cod5 are made by 2 different game studios who produce games for activision. cod 1 3 & 5 are made by trayarch, cod 2 4 & 6 r made by infinity ward.
trayarch really messed up cod5 for PC, I guess for consoles its less annoying.
I hope cod 6 comes out asap... and if you wanna play cod5 with me join our clan server
www.nrns-games.com has the server info.
