I saw this little gem over on hackaday (via digg):
mySQLgame is a quirky App Engine game that has decided to forgo flashy UIs and just stick with the core of the system: a database. You start the game by creating your own row in the shared game database. Game time increments your fuel and money resources every ten seconds. Fuel is spent on scanning other rows and for attacking. Money is used for upgrades and building units. Build up resources and attack your neighbors using database queries, just like any other game. Like a bit more gloss on your internet metagames? Have a look at trolling simulator Forumwarz.
Only for the hardest of geeks, or PhD students like me who were forced into a tenuous relationship with databases. There's no irony there. Hours of fun.
