Pros: Loved the first Starcraft so I figured I would give Wings of Liberty a try. If you have ever played the first version of Starcraft then you know how to play this game. It's not exactly the same, but it is very close. Improved units in addition to most of the units from the first one. Enhanced multiplayer. Gives you the option to play vs A.I or you can team up with with other players and play the A.I. or you can play against other players. This game won't get boring for a while because of the multiplayer (the campaign mode when by pretty quickly). Haven't checked in on the cheats yet (everyone loves a good A.I. game where you just pwn them.
Cons: None that I can think of. Good game, good servers, good fun.
