The first two games are available for those who pay more than the average price.
All the proposed games, except Android, can also be run on Windows (offered in both standalone version and keys for Steam), Mac, and also in Linux (it is possible to get a bundle through the Ubuntu Software Center). As usual, the soundtracks are also included with the games.
IMHO, a very good set this time, especially pleases the appearance of Solar 2 on Android, the best (and, I suspect, the only) star simulator, and also with great music!
