Note: This is an old post in a blog with a lot of posts over a long
span of time. The world has changed, technologies have changed, and
I've changed. It's likely this is out of date, the code doesn't work,
the ideas haven't aged well, or the ideas were terrible to begin with.
Let me know if you think this is something that needs updating.
I added NPCs with heartbeats, adjusted the command handling
a bit to account for exits a bit better and fixed a bunch
of little things. I'll probably build a list of things I
want to do which will probably hinge around adding new things
to the world.
