I've just completed all three single player campaigns in supreme commander.
And am a bit disappointed. The unit graphics are not great, and while the terrain looks good, it's still not special.
The zoom in and out feature works well, but means I spent a lot of the time zoomed out and just seeing the icons for units.
The campaign was not that interesting, and there was no way of affecting outcome.
The maps have a great idea of gradually expanding as you go over the mission, but this meant a few occasions when I built some buildings in a nice safe corner of the map, after completing an objective found they were 20m from an enemy base. Which then destroyed them.
And the enemy ai wasn't too special. Once you've worked out the direction the enemy attacks from, it's easy to defend. And rather than using nice tactics with different units, the tank rush method seemed to work fine.
I imagine multiplayer would be very good, but is anyone else disappointed with this game? I had been expecting more.
