In a former article regarding Linux games a reader commented that for Linux there are always the same title and nothing new really comes out. So i've decided to explore a bit the indie game market and make 2 post about them, in this one i'll show you 5 freely downloadable Indie games, in the next one i'll post 5 game that must be purchased (but the costs are relatively low). So today we'll take a look at: dwarf fortress, epic inventor, abuse, smokin'guns and xonotic.
