Have u played ArmA:Armed ault/ArmA: Combat Operations and IGI2:Covert Strike ?

Ok. I have both of these games and they have about the same difficulty. Getting ArmA and ArmA2 is a MUST because they are both great games with MORE vehicles than Bad Company (EA)! Who would believe it! The online is amazing on both armas and the campaign difficulties are about the same as IGI2 Covert Strike but I cant say for sure as it depends on the difficulty you select on starting the campaign, and of course, the varying missions between the ArmA series and IGI2.
