I am Dilt
I am a man who bought Blockland 7/5/2007, but I've been playing since the initial freeware versions came out years before this, around 2005.
I have been summoned because I remembered an old server that I used to play on. It was centered around building stuff based on in-game currency that generated over time. Those three blocks in the middle were the currency generators. Does anybody remember this ancient server?
