I think it could be whilst playing Advance Wars: Dual Strike for the Nintendo DS. It was one of the final missions, and I had been playing on it for like, two hours, and had reached over 100 days on it. Things were getting tough. I had severely damaged their defence with my Megatank, but they had managed to slip through my defence. I suddenly bought loads of units and surrounded them around the base, and said to myself: "They don't stand a chance!" Days passed, they continued to blast away at my units, but I kept a tight defence.

Meanwhile, some of my other units were attempting to invade the enemy base. I was SO close to capturing their base. Then - all of a sudden...the enemy got a Tag CO power! At first, I wasn't so bothered as my defence was tight, but one of the CO powers was the one that lets them capture my base in one turn. "Ooohhhh, Jeeeesuuuss CHRIST!" I shouted (slow that down by about five times) as I fell to my knees and slumped against the wall, and dropped my DS in disbelief... I fell out with Advance Wars, and we didn't make up for a few days.
