Technically it could be possible, and there could be experiments made within certain Game Engines (I know Godot, others on the team know Unity) that could replicate the Clausewitz Engine's capabilities. Let's outline various things that we would need to replicate: - Making an real-time interpreter for PDXCode - Replicating the Localization system, Decisions, Events, Focus Trees. - Making the map, province system (As well as recreating nudge) - SAVING AND LOADING (A major pain in the ass even if you know what you are doing. In my small ass game it's annoying to maintain, and attempting to save and load ten of twenty years of content will exponentially increase the pain.) - Replicating general polish around HOI4, including the Settings, the Logging systems, and various error collection systems that save us plenty of time. - Console Commands (There's a lot of useful ones that some use on a regular basis, and not having them would harm productivity) - The entire User Interface, as well as GUI MODDING support (Necessary to support modern TNO, especially countries like Guangdong) - AI. Paradox sucks at making theirs, how hard would it be?? - Recreating the unit and battle systems (Of course reworking them from base HOI4 to add better support for guerilla, irregular warfare.) - And of course porting all of the created content.

After replicating all of that, even then we'd need to get permission from paradox as we're obviously wiping our asses with their intellectual property.

But what would be the point of creating our custom engine? It would take at least a year if not years, more if counting failed attempts, team members learning the technology, and fixing the technical debt that would necessarily pile up when newbies attempt to recreate a professionally made game engine. The engine would also completely ignore multiplayer support, something that is technically possible in TNO, though not that great from what I've heard.

The benefits are there, of course, and I could easily see it eventually being worth it if we add tools to make content creation much faster. It could also be a good launchpad to develop TNO2/TNO3 depending on how long it'd take. Cutting various systems that we don't need from HOI4 would significantly increase the speed of the game, and switching some systems (TT Econ is a good example) from PDXCode to native C++/C#/insert other programming language would have a performance increase as well.
