I just finished playing my first StarCraft multiplayer games ever. My brother got a used copy of the base game yesterday for a dollar, and after some irritation with trying to play over the network (hasn't worked for any game I've tried yet - no Diablo II, no Soldat, and now no StarCraft), we decided to try Battle.net. No issues with the CD key and surprisingly minimal lag, so we played a few matches (I won all three). I also got my first taste of playing Protoss, and I've got to say, I'm really looking forward to their campaign.
