A Line in the Sand: The Battle of Iraq
This is a game detailing the Persian Gulf War fought in the early 1990's. Many of the mechanics are similar to that of one of TSR's other wargames (Red Storm Rising) so players of that game can rather easily go to this game.
Combat rules are rather straightforward, and wargamers will be familiar with many of the mechanics. Land (w/ infantry, Iraqi National Guard, and tanks), sea, and air units are all utilized. Most units can take a few hits before removed from the board.
The *real* game, though, is the six-player diplomatic game. The players are now clearly defined: The US (NATO), Iran, Israel, Iraq/Yemen, Moderate Arabs (Saudi Arabia, Egypt, Kuwait, etc.), and Volatile Arabs (Jordan, Libya, etc.) This adds a crucial element of diplomacy and politics, and makes the game much more interesting than the normal wargaming stuff. A "War Fever" and "Jihad" marker change as nations do things--for instance, the first time a US unit is attacked outside of Turkey, War Fever "tripwires" to 10. If Israel attacks a neighbor, Jihad increases by 2. War Fever and Jihad permit certain things to happen--for instance, if War Fever gets too low, the US is restricted in whom they may attack. If Jihad hits either 1 or 10, revolutions may occur--which can switch entire nations to another player!
All in all, the Diplomatic game changes the basic game so much that political considerations are as important as military ones.
