Well there is a resource in MP, in SP the big picture is just preparing for the mission mostly. In squad selection and equipping them (when to carry AT weapons, melee, etc.). You do have more tactical concerns in the actual game, but most RTS games are more T than S anyway. I like the gameplay in DOW2 also as it suits the way Marines operate as the game tells you once "We are a speartip, not an army", base building doesn't make that much sense for them as opposed to IG.
