A great many times. But, that's problematic, it's difficult to remember the details on so many games.
So, the most resent one is on StarCraft 2.
Lost temple. 4 ffa.
2 zergs , 1 terran, me protoss.
Zerg "A" fights terran, I fight zerg "B". Terran gets busted fast and zerg "A" attacks me while my most of my army is away. I almost gg'd zerg B, but had to come back. Since units were lost in the battle with zerg "B", I couldn't win, so I used the phase prism transport to reach the lower right island expo. Had to start from scratch, while expanding to the other island(upper left), got attacked and rolled. From scratch again.... fast tech to carriers, reclaiming the just lost island, while the zergs fight each other (apparently zerg "B" recovered). Then zerg "B" lost, and I hadn't got to carriers yet. For 20 min, I had to stall with blinking Stalkers near the prime zerg base, against high numbers of zerg. But the carriers arrived, and in another 10 min it was gg. The zerg wanted to mass ground and use overlords to get to my base and overwhelm me, but forgot to scout and didn't get AA. His attention diverted by the stalkers.
