Have owned this since release and have to say I had high expectations for this. Notte first starcraft and waited, like so many others, eagerly awaiting the 2nd. Not where I then disappointed. Superbly campaign mode with good story, good multiplayer mode and the game is not very demanding. Played it on, among other things, a pentium dual core processor 2.1 GHz with the 2009 standards rather mediocre graphics card.
My girlfriend also play starcraft on a desktop with a 2.5GHz AMD A4 dual core processor that is 2-3 years old, 4 GB RAM and a Radeon 6670 graphics card.
+ Good story
+ Good multiplayer
+ Good game!
+ Not directly computationally demanding
- No LAN support
- You should have Internet access (not so good for us who sit on mobile broadband)
