I should really keep an outbox because I just had a PM convo about this not too long ago.
First, thanks to RingsOfSaturn for telling me about this thread.
Second, I'm super-busy finishing my college degree. When I'm not doing that I'm wasting my life on youtube and video games.
When I'm not doing that, all "productive free time" is spent on learning a serious grown-up technology, specifically for the purpose of trying to make something that can be of use to Blockland mod creators. I've been chipping away at it for almost 2 months and I'm getting close to the point that I can actually start working on the project itself, rather than learning the tools. I'll probably want feedback from scripters as I'm putting it together, so expect an announcement someday in the coding help forum.
I really liked Rise of Blockland too and I would like to revisit it (or something very much like it) but for now my plate's full.
edit: oh, right, I need to explain why I don't "just release it": Major patches have completely broken RoB, and the codebase is bad enough that starting over from scratch would be about as much work as trying to retrofit it so that the bookkeeping stuff worked again. I don't want anyone trying to build anything out of it because it's a total mess.
