This message appears on the homepage; the asterisks aren't part of it - I've used them to indicate the issues I noticed:
"AudioGames.net is a community portal for audio games: games based on sound. An audio game is a game that consists (only) of sound. Its *gamemechanics* are usually based on the *possibilites* of sound as well. Usually (but not always) audio games have only auditive (so no visual!) output. We think audio games have the *potentional* to be a genre on *its* own due to the immense undiscovered possibilities of sound. Audiogames.net aims to promote audio games and support and inform the audio game community. By providing a clear view on the audio game genre we also contribute to the evergrowing game industry that is only just now beginning to recognize some of the potentials of sound.
