Okay so I use Linux as my daily, so games are a bit limited, and I have always been interested in Kerbal, so is it any fun? I always see strange videos, more from Nerd3(Cubed) and Robbaz used to make them, so would you recommend it for the price, may get it in halloween sales!
With the time I've spent with it it's pretty sweet. Not sure as to what it costs though. For me GMod with spacebuild seems a little... interesting to say the least.
KSP is an amazing game if you like sandboxes and/or space games. Runs great in Linux, too, even with the open source radeon driver. Definitely grab it if it goes on sale, but it's worth the full price.
