Personally I think the semantics on the broader use of the word ‘PC’ (because 99% of people will understand it to refer to PC = Windows) doesn’t really help with the subject.
It is obviously not used in a way to ‘hide’ anything but simply using terminology which is widely understood (even if it is not strictly correct) When people buy the game will have labels on it like any other game with PC, Mac, Linux, PS4, XBoxOne. it’s just common usage.
While, as a Mac gamer I would love to see a Mac client for the Alpha, Beta etc at the same time as the PC one. But I’m realistic that this will probably not happen for a few of reasons;
PC games development mostly happens on PCs and it is natural that the initial development work will be on that platform with a larger pool of experienced developers.
Generally they develop the core of the game this way; get it up and running; then work on porting to other platforms. it makes sense working that way and doesn’t mean the other platforms are any lesser for it.
The broad audience parameters will be fixed early on in the development cycle and will be the deciding factor in what kind of optimisations, support will be in place for the final game. The creation of the clients for other platforms then work within those parameters (based on what is possible and what is realistic)
Reflecting the first point, there are actually very few experience in creating a Mac client/ port which limits the options. I imagine this is also true for Linux. For consoles I imagine there are more. It seems likely from what has been mentioned already, that the team will be looking to take this forward themselves and have staff who have experience in other platforms more generally. This is one of the most exciting aspects of this project for me.
As proposed, this will be the first Mac or Linux game developed and published using CryEngine. Nothing about such a venture will be straight forward however exciting the prospect from a Mac gamers perspective and making promises even before details are made public would be irresponsible.
The prospect of actually playing a Mac game developed using the CryEngine is a large factor in my backing this project. But not the only one. It looks a great game regardless and even if we have to wait longer to play it natively, I can help the development during Alpha via Bootcamp.
