For the price 5.50 (delivered disk) plus extra content from Web (6.69) the game is inexpensive, and is interesting to play, and thus can be recommended to try.
The game was stable, and did not make any "troubles" (in Win7 with 16GB). The game as it came on the disk was quite raw, but, considering it is not the first its year, updates were installed seamlessly from the Web, and I did not see the game at its worse. Installation took some time, it looks like a lot of content is arriving from Internet, and be aware, that this can be much longer than an hour. The new disk arrived promptly, it was sealed and worked well. Supreme Commander 2 includes a more streamlined economy and user interface than those found in its predecessor, with added emphasis on tactics and decision-making on the dynamic battlefield. Also available are "experimental war machines," from a unit that bounces bombs off its massive shield to a vortex-creating monstrosity that sucks up nearby enemies, to influence each side's progress in unusual ways.
Acquire new weapons and technology to outfit and upgrade your army, instantly transforming units into more powerful forms with added capabilities. The single-player game spans 18 story-driven missions, featuring large-scale battles with land, air, and naval units. Set 25 years after the conclusion of the first game's "Infinite War," Supreme Commander 2 has you playing as the commander of one of three conflicting factions: the United Earth Federation, the Illuminate, and the Cybran Nation.
