It does seem that since adding Ryzom to the Apple store, that people have given it a shot who might not otherwise had heard of it. Adding it to the Steam store would likely achieve similar results. Steam might even prove a better advertisement vehicle than the Apple store, because all of the Steam users are either gamers or those purchasing items for gamers.
You are so correct. As a long time gamer I kelt hoping for a great game. It was not until Ryzom hit the Apple Store did I find it.
One way to increase visibility is for everyone to write a review somewhere. I did on the Apple Store and have encouraged others to do so.
I have copies of the download that I give to my Apple friends so they do not even have the excuse of the large file size. But it the software were put on a good looking format and had reps hand out in Apple stores I bet there would be a big jump in Atys citizens.
