Amazingly BAD! Enormous step back.
The game is VERY disapointing... My first impression after launching the game was sth like "wait... is it really a Supreme Commander?????" - I was SHOCKED (and NOT in a good way). If you like first SC DON'T BUY THIS ONE. It's good for kids only - lots of explosions, flashes etc. but VERY LITTLE strategy. It shouldn't be named as RTS cause there is no 'S' ('strategy').
Each mission looks the same.
1. Build defense
2. Build many research centers
3. Wait for upgrade points and buy upgrades you need (or all if you wish)
4. Build your units and crush your enemy with 0 strategy.
IMO even graphics is WORSE than in Forged Alliance.
Someone destroyed a great title... Forged Alliance is much muuuch MUUUUUCH better than this... thing.
