Ugh.. I really regret getting it. Been a long time fan of the original and TA, and it just feels so watered down. There are barely a handful of units for each side, and all concepts of mixed unit forces are pretty much thrown out the window, just spam whatever unit you want to upgrade the most.
Story was bad, graphics were bad, and it just ended up being a rush for the cheap experimentals online, such as the UEF gunship. I miss having to manage my economy, sure it was challenging, but once you learned the in's and out's, it was second nature. It feels more like they gutted the original to try and attract more people, but all they did was turn it into a clone of many other RTS games on the market. I also did not like Steam making me wait THREE HOURS after I bought it off a store shelf before I could even play by myself. Three hours is not too bad, but it still rankled with me.
Verdict: If you like RTS games, and want something fairly quick and easy to get into, SupCom 2 is your game. Or go get C&C 4, its hard to tell the difference sometimes.
