Random project idea that I've prototyped now. An RPG that you play via twitter. The game plays on a server somewhere and you get status updates about the party via twitter. Each status update comes with options which you can select by replying to the tweetRPG twitter account. It's not running live at the moment, so don't bother joining just yet but here's a run of me going through a rather poorly written single level adventure:

@cac Party: Ormon (Archer/1 [10/10]) Wot (Warrior/1 [10/10]) Baz (Mage/1 [10/10]) 
@cac Into The Lair: The Goblin King has stolen the Orb of Kain, enter his lair and retrieve it
@cac The party enter a dark cave, the only known entrance to the lair
@cac The party run into a band of 3 goblins. FIGHT or RUN?
@cac You run! Some of the party are hurt in the escape! Ormon [10/10] Wot [10/10] Baz [10/10] 
@cac The party come across 3 goblins. FIGHT or RUN?
@cac The goblins are defeated! Ormon [10/10] Wot [10/10] Baz [10/10] 
@cac The party run into a band of 4 goblins. FIGHT or RUN?
@cac The goblins are vanquished! Ormon [10/10] Wot [10/10] Baz [10/10] 
@cac The darkness lifts to reveal a room containing a small chest. IGNORE or OPEN?
@cac The chest is trapped, the party are hit by darts.Ormon [8/10] Wot [8/10] Baz [7/10] 
@cac The party come across 3 goblins. FIGHT or RUN?

@cac The party enter the throne room and recover the Orb. Quest Complete!
@cac There are no more quests available.

So, the party was generated and go through the adventure asking you for input as and when they need it. The code (which I'll release in a bit) was a pretty simple affair thanks to the wonderful Twitter4j. Hopefully soon you'll be able to follow tweetRPG ad join the adventure. Ok, it's not that exciting but it's pretty open ended and was a bit of fun to write.

You can check out a the little website I put together as a help page and sort of short explanation of the idea. I don't spose it's the first idea for a twitter game or the last, but silly it definitely is.

<quest name="Into The Lair"

               <range low="1" high="3">
                  <damage low="1" high="3"/>
                  <message txt="The chest is trapped, the party are hit by darts." 
                              hp="true"/>
               </range>
               <range low="4" high="6">
                  <gold low="50" high="300"/>
               </range>
            </roll>
         </option>
      </room>
   </level>
</quest>

The best bit is that the quest description has brought out of a series of issues for Yore's development (see the XML above). Cross project pollination for productivity!
