I'm not arguing competency, I'm arguing resources.
It takes Feral Interactive between 3-4 years to port a Total War game to OSX(usually 3). The Creative Assembly is more or less on Track to port Rome II over a 2 or 3 year cycle at this rate. Sega Hardlight has only ever ported to mobile and Windows.
I'm saying, that these games take time, so while Sega is capable of porting(Which I never argued), it will still be a considerable wait.
