If the author is reading this, I highly recommend you look into the history of text adventures and MUDs (multi-user dungeons), as the post completely omits them despite the fact that they are almost literally "RPGs with command-line interfaces". While old-school text adventures remained fairly primitive in the RPG aspect (and new-school text adventures have trended away from the RPG genre and into interactive fiction), MUDs represent the logical conclusion of the thought process here. For reference, check out DiscworldMUD (http://discworld.starturtle.net/lpc/ http://discworld.starturtle.net/lpc/), which is still actively developed and can be played in your browser: discworld.starturtle.net/lpc/decafmud/web_client.html
