UPDATE 7TH JUNE: What. A. Thread. I've laughed, I've been watery-eyed, and I've been taken back to the carefree days of my childhood. To everyone who took part, thank you. Seriously, thank you.
It's taken me a long time to decide upon a winner because there are so many brilliant memories. I've said it before about the Zelda and Star Wars memories and I'll say it about the Street Fighter memories too: if anyone ever asks you why people play games, show them the comments here. They warm my nerdy heart.
There's something slightly different about the Street Fighter memories, though. I notice themes emerging from the memories of each game, and a big one here, which is fundamental to what the game is about, is competition - and with it, rivalries. There have been some spectacular stories about overcoming challenges and beating - or being beaten by - an incumbent champion. Shout out to MrE26 (search for their names and you'll find their comments), turbografx16, Faseli and Neuroniky in this regard. Neuroniky, I really felt for you!
