I've created a new bot called SimpleStatement, which plays a very simple sentence game with the user. No, it's not as much fun as Quake or Grand Theft Auto, but it's still a game.
The user types in a simple fact of common sense, such as oranges are round or whales are mammals. The bot responds with a statement that is somehow related to the user's. The bot learns by storing the user's statement and using it later. NOTE: there is very little data at the moment, so expect the bot to repeat itself and state incorrect facts.
You can ask the bot <*lazy*>very*lazy*> simple questions. Only questions of the type "what is a monkey?", "what are tigers?" and "what things are mammals?" are currently implemented.
This game is very much like my old bot 'AWordExperiment', which played word association with the user. These bots learn from players through natural conversation and corroborate the data they learn so that they can weed out false and fake data and get to the true facts and word associations. They even learn how to spell! (If you played AWordExperiment, you'll remember that it learned how to spell simply by playing the game!). They also develop a level of trust in their players. Players that continually tell them incorrect facts or garbage tend to not be trusted as much as those that teach them truths.
The game is still heavily under development, using a built-from-scratch bot system and I hope you'll try to play it with a good spirit and not just feed it garbage. Improvements to come include the ability for a player to disagree with the bot's statements and a larger group of possible questions.
