I originally bought this game as a hard copy so my steam account hasn't logged the probable 100+ hours of game-play I've had from this game.
A fan of the old Command & Conquer games, this appealed and did not disappoint at all.

Firstly, the game play can be picked up very easily and the campaigns are a great way to get to handle the more in depth details as you play through the game and also the factions.
This game, however, came into it's own with the Skirmish option. Single player is always fun to pass the time and release stress by pummelling several opponents into dust. BUT for maximum enjoyment definitely has to be multi-player.
Once my friends and I hooked this up through a network (internet also) say goodbye to a decent nights sleep. The battles were epic, the scale was huge and most games started out as build a HUGE army and just slaughter your friends.
This does get a little overpowered at times but with the options to ban certain units/grades, etc. Then the battles became more interesting.
A friend would attack, you'd figure out a good line of defence, they go back and try work around that defence, you attack your way, they figure out another defence, etc... it was ♥♥♥ for tat battle that kept your ideas and strategies rotating and constantly developing.

In the years I've owned this game, it's never lost it's appeal. The graphics are nice & finely detailed, controls are very easy and bulk unit commands are simple, way points & patrols are easy to set. All in all a great strategy game BUT I'd highly recommend multi-player for a long lasting experience.

(After SupCom, I'd purchase C&C 4 and was very disappointed. Thinking about it, I've not played C&C since but instead gone with the SupCom expansion and SupCom2)

together with forged alliance this is the best RTS i have played so far.
avoid supreme commander 2, its a dumbed down shadow of its former self.

I've only put an hour into this game as of recommending this, but I have to say, I'm definitely going to enjoy this game. The problem with many other games is that making a sizable army can take forever, and it never really feels like a true large scale battle (the only exception I can name that I've enjoyed being Battle for Middle Earth 2, when you can have 5+ barracks sending wave after wave into a battle zone).

This game takes large scale strategy warfare to a whole new level, even introducing artillery that can fire for seemingly kilometers right into the enemy base, bringing a hint of objective gameplay into multiplayer matches, where you may be forced to take out the enemy artillery to protect the integrity of your base.

I have encountered issues launching this game on Windows 7, however, but that was solved by launching the game in Windows XP Compatibility mode, so it's not a major issue.

To keep it short, hell yes, I recommend this game.

epic sci-fi battles. huge armies. awsome graphics. I haven't tried it online tho. Is fungame.

It's got a mediocre story but it's a good RTS and the mechanics are brilliant.
