just “linux” in daily public speech is definitely the way to go branding-wise. no random pedestrian is gonna know what you’re talking about if you say GNU or Kubuntu or whatever (and they probably won’t know “Linux” either, but the chance is marginally higher)
loved everything about both games! the sequel is LONG, so it might take you a while. but it tells a great story :)
my only tiny gameplay gripe is the same gripe i had with god of war: ragnarok. if you’ve played both, you know what i mean. but that’s crawling into spoiler territory. also running around looking for resources gets a little tiring sometimes. enjoy your playthrough!
