I would have to begrudgingly agree that cli games would include all infocom games would be command lines games since it doesn't have to be constrained to the command line shell like /bin/sh
I forgot to mention after my comment "play by email" games which would broaden the scope to network games since the interface could be through a shell when using sendmail.
Play By Email seems marginal. It's certainly true that you can do it from the command line (I'd heartily recommend nmh over using sendmail directly), but it's sort of incidental rather than by design. That said, I'd count it.
I agree. What I think makes PBEM marginal as an example of "command-line-only" is that it is designed with email in mind as the interface, and it is only because we have command line access to email that we have command line access to the game. As I noted, though, I still think it counts.
