Thank you so much!
I've considered it but there are several big issues regarding it. DOS, for example, is 16-bit, so a lot of the existing code simply wouldn't work to begin with. The PS2 has its own set of functions to interact with its hardware and I doubt the CPU is powerful enough to run King's Crook as quickly as I'd like. And it's not just performance that will suffer, there are also RAM limits on older platforms that are tricky to get around. Another factor is input--King's Crook is designed as a PC game with mouse-look and a large number of keyboard bindings, this wouldn't translate well to a console. My goal with King's Crook is to make a late 90s, early 2000s PC game rather than a game that could've been run on retro consoles. But yeah I've definitely considered (and in the case of DOS, tried to) port at least the 3D engine to the platform but it's way too large of an undertaking for me.
I appreciate your support and I'm glad you asked this question :)
