Stage select:
1. Beating the original Legend of Zelda before my friends did.
2. My first ever playthrough of Final Fantasy VI, I was fighting Atma Weapon (last boss of the World of Balance), he wiped out all of my party members except Mog, who was stuck in Dance mode where you can't control him. I went off and made a sandwich figuring I was screwed and not happy about it because it took so long to get there. I get back after eating my sandwich and Mog is doing a victory dance. I'd won the battle.
3. Beating Dragon Quest VIII with my wife, who I'd just married at the time. We played together along with my stepdaughter.
