A1.) Play the original on Dreamcast
A2.) Play the original two games emulated (probably the most played games on DreamCast emulators)
A3.) Play the 2018 remaster (Shenmue I & II HD) on PC (was included in a Humble Monthly Bundle)
A4.) Play the 2018 remaster (Shenmue I & II HD) on PS4 (probably on PS+ within the next 3 months)
A5.) Play the 2018 remaster (Shenmue I & II HD) on XBO (free on GamePass!)
B.) Be one of those who actually enjoyed it
Thanks to emulators, PC bundles, GamePass and probably soon PS+ the fan base should have grown a lot in the last years.
A3, A4, and A5 are covered in "E" of the original post. But we'll see if the game does well. I hope it does.
