... I sadly won't have a machine that can play 6 until long after it comes out :kitty-cri-texas:
Lots of people here would like the series though -- tons of anticapitalist themes throughout, fun gameplay that's different from soulsborne stuff, but scratches the same basic itch, etc
As the guy says in the video though, getting the older games is needlessly difficult if you don't go the emulator route, and something I'm hoping for with 6 is that it leads to re-releases of the older titles as well (once again pirates have been doing most of the work of content preservation, God bless them).
Did you play Daemon X Machina? It's an ACish copycat from a few years ago - originally launched on nintendo switch so it'll probably run on a broader range of hardware.
AC6's getting a PS4 port, as of now anyway, so I can't imagine it'll be that resource-hungry. Fromsoft is thankfully resisting the western AAA trend of making your games as visually expensive as fuck.
