I remember being introduced to BL in... 2009, I believe?
I was a dedicated Roblox player, and my friend Alex called me over to his house. "Dude, you have to see this!" I hopped on my bike and rode up to his house.
He was at his laptop, playing the demo of "Blockland".
I watched for five minutes and said, "Oh my god, that is so much better than Roblox..."
Month later, I was a Blockhead. :D
