Off the top of my head, the masterful ownage Becky gave me at SupCom springs to mind - 4 players (me, John, Dan & Becky) - John was the strongest and so we agreed to take him down first, Becky was furthest away from John. I had the strongest economy, so sent my army in, wave after wave of slow progress, Dan did the same but on a smaller scale (because he sucks), and Becky built up a mahoosiv air army which she sent finally sent about half down to finish off John - now me and Becky were tied as the strongest players left.
At the same time she put her commander in the transport plane, she said she'd moving everything in on John, but have a 2nd wave ready - the 2nd wave parked over me & Dan's bases, and after John fell she left the alliance - meaning my AA guns suddenly started shooting at the transport - when a commander dies in SupCom it sets of a nuke and so my base/economy was screwed and she finished me and Dan off with ease.
In fact SupCom rocked - Same for when I bombarded John with millions of Tech1 bombers after a 40 min no rush - there were so many he couldn't take 'em down in time and so I got his commander
