Simply, one of the best RTS games by even today's standards. Recently played on-line for over 4 hours with zero issues. If you are a fan of "thinking" RTS games where strategical decisions are as impotant as the tactical ones, then this game offers it all. The AI is superb & can be tweaked to your liking via text files for an endless supply of all types of playing styles.
The multiple victory conditions, outstanding RMG, excellent UI, wonderfully stable game play, excellent end game stat screen, a video file to watch your/other's replays, modding is possible, etc, etc. This game was done right.
