I have a little over 80 hours logged into this game. I have played the full base game, and I am currently playing the U.S. Marines series. Whether new the tactical, turn-based strategies games, or if your gameplay legacy includes the great Panzer General by SSI, I think you will enjoy this game. Each mission provides unique challenges, on land, sea, and in the air. Sometimes, you will have to coordinate on all three. A significant improvement over older tactical strategy games such as Panzer General is the supply system. It is not enough to simply click the re-supply button and wait one turn. Players must now strongly consider maintaining lines of supply, and protecting them from the enemy, and the enemy will try to cut off your supply lines. This will cripple your offense or defense! The base game will be enough to keep most players entertained for many hours. But, the game also has nearly a dozen series expansions, focusing on different campaigns of World War II, from both the perspective of both the Allies and the Axis. Order of Battle also has series expansions that focus on campaigns of World War II that are often overlooked in many other war games based on the WWII era. The only two downsides I can think of is while the game has many interesting series expansions, they cost between $9-$14 on average when not on sale, making Order of Battle a potentially expensive game. The other downside is the scenario editor: it works and has many options for the player, but almost not guidance in the game or in the manual are included. In conclusion, if you enjoy tactical strategy, you can hardly go wrong with Order of Battle.
