Here is a link to the recently posted Kenshi/Kenshi 2 Development News. Chris Hunt says they've switched Kenshi 2 development to the Unreal engine. Moving original Kenshi to that engine would slow down production of Kenshi 2 'significantly' so they're asking player opinions on a Straw Poll.
Personally, I voted for not switching Kenshi over to Unreal because I'm excited to start wiki-ing about Kenshi 2.
Porting the game over to Unreal seems like a bad idea to me. They're used to working with Ogre, and although I've personally never worked with that one, I can tell you that UDK wasn't the easiest for me to use when I tried my hand at it. Mainly what I worry about is an excessively sized game (plenty of modern ones weigh in excess of 80 gigabytes) and delays caused by the newer version of Unreal being subscription-based.
Maybe it's just my biases, though. The games that I've worked on were never more than a few megabytes and rarely took so much as a gigabyte of ram, save for a Half-Life 2 mod that never got released. Maybe the dynamics are reversed when working on something the size of Kenshi.
Still worried about the final product being like a terrabyte.
