Suggest a text based game

[oracle]

Hello Friends,

I have started a website http://gtalkbots.com and one of the features is online text based games on your Gtalk itself.

Right now I have only one game, Anagram which one can play by adding games@gtalkbots.com in his gtalk messenger.

However I am looking to add more text based games, but I am unable to find interesting addictive text based games. If we have a game freak here, can someone suggest a few which can be implemented

Regards,
Imoracle

I'll have to take a look...Good idea!

How about Hangman! (Not sure how difficult it would be to implement though?)

Any sort of alphabet game, like I name something starting with A, someone names something with B, etc. Or trivia.
