They tried to buy Serious Sam VR as well. It wasn't easy, but we turned down a shitton of money, as we believe that truly good games will sell by themselves and make profit in the long run regardless. And also because we hate exclusives as much as you do.
Dat shitton of money tho...
Edit: Wow! Thanks for all the support, you guys rock! We love you and we love making games for you!
Edit2: Please don't hate on other devs too much, I'm sure some of them didn't have financial alternative but to accept such a deal in order to even see their games finished. In such situation, anyone would have done the same.
