A week or so ago, probably a bit more since I take my sweet time these days there were some announcements made. These announcements had two things in common. They were about the game engines, and they were about future of free game engines. I am talking about the announcements regarding Source 2, Unreal 4, and Unity 5.
If this was a poker I'd be waiting for a 3, 6, or an ace at this point for a straight.
As I do not really know a lot about the game engines I cannot say much about the technical side of things. What I can say though that in this case free means a lot of good things for the gaming in general. We have all probably played more than just a couple of games made in these three engines or their direct predecessors. And just from our own experience we can say that the technical side of these engines is in general nothing you can complain about.
