I fact I'd really like to play WW3 in 2015 rather than in 1985. A rather realistic scenario. The scenario would be like this:
Nato + Israel to declare war to Iran. Coalition forms with Syria, Pakistan (etc.) against Nato.
Possibility for Russia and/or China to join "axis of evil". Possible entry of Venezuela and North Korea into the Axis "of evil" tpo bring war in south/central america and Asia.
War could spread to Africa with African states divided between Nato and "Axis of Evil".
Global conflict with nuclear and other non conventional weapons.
Guerilla and "partisans" troops in Afghanistan, Africa, etc.
Possible VP could be (among many others) to destroy (or protect) oil fields in middle east, controlling natural resources in Africa.
Bombing (or protect) Israel for axis (for Nato),
Sending missiles abroad for N. Korea and damaging Japan, S. Korea, Oceania, etc.
All this with a good and realistic simulator like Command: Modern air/naval ops..
Would be quite great to play (in game, not in real of course!)
