I never give up, never, so I searched and searched deep in the internet, Indie games are the solution.
Indie games are the most profitable source of entertainment for us, Linux gamers, or even for our competitors, Mac and Windows.
Even starting with some paid content(which is good to increase good content), we can see it's a very good point for great game creators.
So, What games do I recommend?
Indie games are the functionality that are gonna make linux great one day, so show them support as soon as you can see you can support them, because you deserve to enjoy something good and they deserve to be supported.
