... 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).
You know anyone who bought a new console but has an old Xbox One / PS4 lying around? They might let you borrow the old console to play AC6.
I haven't played the series since the first one, but I remember loving it and then being weirded out playing Demon Souls in like 2010 thinking "wow, this is the Armored Core people?"
