Hi folks, according to the article here: http://lgn.linux-hardcore.com/gnulin...ng-phased-out/
Grubby Games is now phasing out Linux support, because the company they were bought by wants everything to go thru them, and that company has no plans for a Linux gaming section.
Sadly, that would mean that any games by either company would have to be considered not possible for ports as well.
The games are still up currently, but there's no word on how long they will be up.
At $6.99 a game, it's pretty cheap for some puzzlers, and a game that sounds a lot like Populous.
Here's the link to their games: http://grubbygames.com/linux_games.php
