It really depends on what init system you want to learn.
Right now, you’re learning BSD init. Which is not the same as the non-sysd init systems in use on Linux. Perfectly fine system mind you and they share some overlap with their Linux cousins.
As much as a very vocal subgroup hates to admit, systemd is a pretty core aspect of modern Linux.
That said if you really want to learn an alt init system gentoo lets you pick, and I think Slackware is still sans systemd.
Oblivion.
Daggerfall was awesome and Morrowind blew me away. Going into Oblivion I had the highest hopes. Bought the Collectors Edition, took the day off…and biggest disappointment from a game ever. Granted I like Skyrim. Not as much as Daggerfall or Morrowind, but far more than Oblivion. So I guess it didn’t kill the franchise for me.
Bonus popular game that actually killed the franchise for me: GTA4. I loved the Trilogy, but I could not stand IV. All the main characters annoyed the piss out of me, the driving and gun play weren’t nearly as fun…I tried to play it but got burned out around 1/3rd of the way in. Tried to play GTA5 a few years ago and I felt burned out after 40 minutes.
Amazing tool but sadly abandoned and slowly getting more and more unstable and difficult to build
The better options:
Now that I think about it, I believe Slackware actually uses a BSD style init if you want to try and bridge the gap. It’s been eons since I used it so not 100% sure
