I thought AiO was a standalone mod?
Nope, it required Vanilla Blockland to run.
AiO-
r however, did get a few iterations that were packaged together with an unmodified copy Vanilla Blockland just so people wouldn't have to download both.
I think it was Lanhoj. I know he made AiO and something else. The "something else" might have been it.
Also at the bottom of the page "2005 - 2011 Just kidding." Haha.
In relation to Blockland, the "something else" from me (with help from a few others ) you might be referring to was most likely AiO-
r.
