Well, you'll probably end up having to rewrite the code nearly from
scratch and heavily overhaul the gameplay to make a mud out of it. But
that's ok, most of us approach our muds as iterative processes anyway.

This'll likely be a problem once you build a mud server due to
reentrancy issues. You have to either make it reentrant or parse the
entire sequence of commands without allowing other player commands to go
through.

This is another problem. What if you want to allow "get the knife" and
"knife the innocent victim"?

The biggest inefficieny being that you store everything as strings. A
better approach would be to analyze each word independently first for
classification and tokenization.
