Didn't I read that it took two years to port it? So not so easy as clicking the "port to pc" button (/s). But yeah, I'm sure Sony is very happy about this. And hopefully that means they launch games a bit sooner on PC too!
Yea, fanboys will be quick to jump on that and overlook the fact that this was a TINY core team working on this for the most part. Probably didn't cost much at all to port this game, considering that. They're probably going to make a 30-40x ROI on this game for this game over the life of the product.
Sony knows full well that this is a different platform and that they are going to have to build a solid rapport with PC gamers to build up their franchises on the platform. What they will be looking for is continued growth for sequels to games being released.. ie Horizon 2 and Ragnarok.. and it seems to me that they are putting in the work now to ensure that porting is as easy as possible for future games. It's important to remember that games like Horizon ZD, and God of War were completely created and authored around the specific console hardware. These ports and Sony's new push into PC gaming means that games like Horizon 2 and God of War Ragnarok will likely have introduced pipeline changes in how they build and approach different development issues. Thus making it easier for the teams porting the games in the future.
I think it's fairly clear right now with the information out there, that Jetpack Interactive is quite ingrained with Sony Santa Monica now, and that they have simultaneously been doing a lot of the initial work alongside SSM on Ragnarok to help make the porting process easier in the future.
