It's absolutely worth $30-$35, but $50 seems a hair steep unless you've been dying to play it. It's a top-tier game with a sort-of open world, but it absolutely isn't another Ubi game. The open world part won't even show up for HOURS. I may pick it up on PC at some point, but oh boy do I have a huge backlog that I'm finally actively going through. Part of that backlog was Ghost of Tsushima, which runs at 60FPS on PS5 without the "PS5 upgrade". Absolutely fantastic, I hope it ends up part of these PC ports so more people can play it. The primary story didn't hook me; the side stories of other people did, as did the pure FUN of its savage/graceful combat.
Unfortunately, it seems Sony only does these ports when it's going to point out that a sequel is looming, but only for the console. Ghost may never get a sequel, the story is quite complete, so...it may never see a PC release
