I think there are a lot of people on here that do not understand what parser-based interactive fiction is. ParserComp came about because there was a need for a competition exclusively for parser-based interactive fiction. It is not for choice-based games or role-playing games or simulations or point 'n' click games or hyperlink games or fill-in-the-text-box games or arcade games that call themselves adventures. There are plenty of other game jams and competitions where all these other forms of games can compete. I have nothing against these other forms of games, but they aren't traditional text adventures or parser-based interactive fiction.
Parser-based interactive fiction is a form of artificial intelligence that uses natural language processing. It is where you type a command and a parser breaks that command into individual words, identifies the parts of speech and does pattern matching in accordance with some grammar rules. It then determines the actions to be performed, carries out those actions in accordance with the rules inherent in the world model for the game and prints a text response to tell you what happened. If your game doesn't do all that, it's not parser-based interactive fiction.
The organisers have already been very loose in their interpretation of what is acceptable for the competition, but you have to draw the line somewhere. If a game is clearly not parser-based interactive fiction, then it is outside the rules and should be disqualified. Otherwise the competition becomes a joke.
