WOW! sounds like a very cool game! I agree with CountZero that this thing doesn't appear to lend itself well to a single regex per command entry.

I suspect that you will wind up saying doing a first pass that just identifies the type of tokens on command line: alpha numeric alphanumeric. So for example from what I can tell an alphanumeric thing is always wrong "Speed10", "10speed", or maybe not? - I'm guessing "speed 10" and "10 speed" would be ok, but a "run-together" thing combining 'speed' and '10' isn't valid. If you put regex code that says that "10speed" isn't valid into each command "regex", this could get to be a very big mess!

I think that you are into quite a bit more than regex'es and will need a parser of the command line. But depending upon the grammar, it may not be that complex and is perhaps even easier than the regex type approach.
