... 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).
I mostly remember being awed by the Ghost Bear's Legacy intro cinematic where the Kodiak bursts out of the ice in front of a Raven and constantly overheating because I used as many large lasers and PPCs as possible.
