@Piano player hello and welcome. Feel free to join in the discussion about audiogames, hope you have fun on the forum.
@Sasha Hi and welcome, always nice to meet another Nintendo fan (My Snes is still setup about six feet away from me ).
The best way to learn about audiogames is to play them. I started on audiogames myself when mainstream games became too graphically complex for my vision, which let me play a lot of game genres I'd not had access to such as Fps, rpg etc, I then found audiogames had quite a lot to offer even in arcade titles (imho packman is actually more fun in audio than graphically since you need to remember the maze).
There are a lot of titles around to try, everything from Swamp, the audio fps, to the recently released first person rpg a hero's call, manamon, essentially audio pokemon, and of course various arcade titles, most noteably the wonderful online battle game crazy party, not to mention audio stratogies like sound rts.
Just have a hunt around, particularly in the database at the front of the site, play some games, ask questions and you'll hopefully get an idea for what works, indeed one of the main problems developers often have is that they ahven't considered what's already been out there.
Oh, and as for political correctness, that's not really an issue, indeed you might say we're blind to such things, though you might say a lot of people here are blind anyway, which would be the truth .
Seriously, any general questions on netiquette just look at The site and forum faq found here though interestingly enough that doesn't have any questions on political correctness, or what language to use, hmmmm I wonder if we should add one?
