CoD2 was scripted, very scripted. many interactions couldnt be avoided. I think it would make for interestign gameplay if, instead of slecting a difficulty level, the missions and objectives were totally your choice, with the only objective you must do is get from point a to b. Objective slike destroying missile silos, invadeing bunkers, clearing out sniping lcations, destroying tanks should be all secondy objectives, but all have varying levels of difficluty, so if you wanted the game could be very difficult.
