I remember him just because my POS software was the only "competition" to Afterblock.
edit: Oh hey, I'm actually mentioned too.
"It was announced prior to Platnium Blockland, which IcyGamma always felt stole
AfterBlock's concepts. Though Tyler66, the developer of Platnium, denied this."
I still stand by that, I had no idea about the existence of AfterBlock when I was working on PBL. It all started when I had the idea make a simple "Blockland Manager" which did simple functions like automatically find the Blockland directory and open folders.
Looking back on it, both were equally terrible for one being worked on a novice Visual Basic programmer and the other being made with the GameMaker library, something which seems a rather odd platform to be developing your application on.
Overall I don't think anyone asked for either AfterBlock or PBL and both were just about useless and completely unnecessary in concept.
