Ports are awful because of the controls, GUI’s and settings are being made for consoles and their controllers ie. dumbed down. A good example is Borderlands, which had a shit gui and gear management system. Some games have little or no settigs for FOV etc.
I enjoyed Forward unto dawn as well, considering it wasn’t a huge budget show. I’ve seen it like 6 times and I’ve never even played Halo, so I’m very much in the dark lore wise.
