It wasn't a jaw dropping trailer. And to be honest I'm not really intrested in Starcraft 2. To me Starcraft 1 wasn't as good as an RTS as everyone claimed it even with all the expansions I had it felt week, I still perfer Age of Empires, even after the horrible turn they did at the 3rd one from how vastly different from the second, it still felt like an RTS, Starcraft just feels like build a bunch of units and send them in and watch. Age of Empires made you think of all the different usint as they all had MAJOR strengths and weaknesses, meaning I couldn't build 50 battering rams and send them in like tanks, as they would be destroyed almost instantly by infantry, so you build 10 battering rams, 10 calvary, 10 archers, and 20 infantry. And even then you have to use a battle plan and grouping. Thats what made it fun, Starcraft just felt like a click this unit watch it kill.
And yes, before anyone says anything I still own Starcraft 1 and I did play it.
