Well, first of all, to add to the list of countries:
Norway, rushan, poland, canada, Iran, and surely there are some more.
If you ask me for tips on audio games, depends on what you are looking for. We can't give you as much as for the sighted possibility but I think that about 350 games is enough for me and I haven't tried a bunch of 20 at least. And there are more games right now at the moment that are being developed. The most popular ones are: (From my opinions)
Entombed, Sound RTS, Battlezone, Topspeed2, and there is a newly developed "3d-vilocity", which sounds quite good. In the RPG's top is Entombed, but if you want to train your ears take a look at: Shades of Doom and the other in the serie of 3d games. Look also on topspeed2 and Battlezone. Battlezone is a 2d game that is being developed by Key is Full on this forum, and Topspeed2 can be find at:
This is just my opinions, and those are just some examples, and there is loads of other great games.
