Breath of Death VII does not have any prequels.
Ogre Battle: March of the Black Queen was subtitled part 5, as Ogre Battle was intended to be a 7 part series, but only 4 games got released.

I tried it because even with most of the bloat disabled Microsoft still kept threatening to downgrade me to windows 11, so having heard most games were working through proton and knowing gimp and Firefox run natively I figured it was worth giving it a try.
I stayed because with KDE it feels like an “unlocked” windows, windows with all the annoying parts stripped out, delimited, or fixed. Installing it was simple, customising it was extensive and easy, games run better, GIMP loads faster, installing programs from the bazaar is trivial, and it doesn’t run into any more bugs and errors than windows did, so it’s just a net upgrade. Weirdly bugs are often easier to diagnose and fix with the help of a search engine too, because the questions and answers tend to be a lot more in depth and informative than you get with windows.
