Supreme Commander's ancestry is immediately apparent when the game is loaded. Numerous elements of the game are similar to that of Total Annihilation, including the use of a commander unit to build your army. Now called the Armored Command Unit, this unit is all you start a match of Supreme Commander with. The ACU is no slouch, however. The ACU is not only the most effective individual construction unit in the game, but is also an incredibly effective combat unit, capable of taking down numerous foes. Upgrades can further increase the abilities of your ACU, making it on par with the game's most powerful super units. Yet, in spite of the ACU's unique role, Supreme Commander is clearly a macro-oriented game, focused more on troop movements then the tactical use of individual units. Building units in Supreme Commander is quick and easy - you'll likely have a larger army in the first ten minutes of Supreme Commander than in an entire game of Dawn Of War. As a result, the basic feel of Supreme Commander remains similar to that of Total Annihilation. The decisions to keep a full compliment of naval and air units in the game reinforces the similarity, although naval units feel tacked-on.
Unfortunately, Supreme Commander stumbles far short from perfect. The largest problem is that while the game provides an incredible rush when its strength - the possibility of massive combat involving multiple players and hundreds of units - can be experienced, these moments are far to rare. While the game makes attempts to prevent rushing, including the option to add a no-rush time limit, these attempts to increase the game's length often fail. High-level ranked matches of Supreme Commander are short, and the game's simplistic and disappointing low-end units means that such short matches never compare to games like Dawn Of War or even Starcraft, which are designed with short matches in mind. The game also suffers from a lack of balance, which in some cases mirrors imbalances that plagued Total Annihilation. Air units, for example, are far too deadly - having the most powerful airforce nearly guarantees victory.
