We tried ue4 and godot as new engines, but those didn’t work out because ue4 had weird bugs with physics (with different behaviour in linux and windows) and godot’s shader language was too simple and restrictive.  
Now we’re adapting thrive to @hhyyrylainen’s engine Leviathan, which has a lot of libraries in common with thrive.
