I am interested in the game series, but it looks like there are many points to start from. Myst 2021, realMyst Masterpiece Edition, Myst Masterpiece Edition, Riven, Riven 2024.
Seems like the starting point is a relatively controversial topic amongst fans. I thought of starting with Myst 2021, then playing the original Riven.
Both are fine choices depending on your requirements. The thing with external alias services, you are not in control of the addresses/domain. Catch-all addresses are essentially aliases you manage, but something like Simplelogin does have the benefit of hiding your domain name.
Spam is not a big deal on catch-all. A couple of times a year I do get a spam mail to some arbirtary address, but that’s more or less it.
