We are not exactly active in the Android scene, how ever we are working at a online roleplaying game and we are always looking for new developers.
There are currently nearly 30 people in the development team. That means 3 server developers (C++), 1 client developer (Java) (Thats me! ), 1 graphics artist, 10 game mechanics and content developers (Lua) and 1 web developer. The rest is working in translations and QA. In addition to that there are 8 people who handle the player management and the in-game events. In addition we got some arrangements with 2 sound artists who supply the original sound track to the game and 3 people who handle the society that maintains finances and the rights to the game.
The project is active since '99, so we got beyond the point of the initial idea.
So if you want to join a active team, feel free to contact me. You can look in what ever part of the game development that is done here you like.
The projects homepage is: http://illarion.org
We also got parts of our source code as open source: https://github.com/Illarion-eV
As I said we are not in the development of android applications. How ever we can provide experience in general game development and game management. And we got a small, yet active community of players who give us some feedback.... for the better or worse.
As for the languages. The game is in German and in English. How ever most of the development and playing is done in English.
Feel free to contact me if you are interested.
