Larian Studios (developers of the Divinity games series) have announced plans to release their upcoming RPG "Divinity: Original Sin" on Linux as well as other PC platforms! Soon, Linux will have a great RPG to immense themselves.
According to kickstarter, the project has been funded fully within a good heap of time:
Divinity: Original Sin is an upcoming RPG which in my eyes would be a combination of Skyrim's vast world to explore with Divine Divinity's traditional RPG environment of a classless system, much like in Skyrim. More details about the game are in the above links.
What more is that the guys at Larian Studios are promising more content the more people who fund their project. I think over the years they've done a great job, and the fact they're joining the trend in Linux gaming is a big plus. Although, they haven't said which 'side' of Linux they're gonna release the game in, I'm guessing it's under Ubuntu. I've already added my support for the project for more content.
