If you haven't played any before, your first question may be: Why would I play a game made up just out of text? The IFComp is a good place to start. It really helps to what really talented people can do with the medium. Here are two worth playing:
Inform7 is a very widely used tool for making IF now (http://inform7.com/); I haven't played with it much, but from what I've seen, it does some really great stuff. It's a good way to get started writing your own games.

There are many DSLs for just this purpose that almost always should be preferred to a general purpose language like python. http://www.ifwiki.org/index.php/Inform_7 is the most commonly recommended.
I wrote a little game engine for the purpose of LPTHW... went a bit beyond what was required. The Inform 7 guide was a great tool to help. It probably is true that if you want to actually create a game that would be the way to go, it appears full featured enough to port just about any game out there.
That said, if you want to understand how such an engine works, it was alot of fun creating something in Python.
It's a community for making and sharing interactive fiction (aka "text adventures") entirely from your browser, using a crazy-ass "natural language"-inspired language called Inform 7.
Some stuff is broken and missing, lots of rough edges.
I love text adventures (P&C, too) and I always enjoy using them for teaching purposes. If anyone is interested in picking up Prolog anytime soon, I really enjoyed this tutorial:

I wrote a cool iOS Text Adventure game framework for anyone interested, I was thinking of porting it to ruby motion but the niche I was going for ( learn to program ) probably don't have the cash for a Ruby Motion license.

1) Taco Fiction (http://ifcomp.org/comp11/play.php?id=201) and
2) Violet (http://jayisgames.com/games/violet/), both previous winners.
