Um, not sure if you’re joking or just young, but you have heard of this thing called Unix, right?

Yes, I know about it, it's just that Linux come first to mind due to all the early discussions about it being Torvalds' toy project. Plus I assumed Unix supported also other architectures, given how much variety there was in the early days.

Leisure Suit Larry predates Linux by quite a bit (as I recall the first 8-bit versions of the game came out in the early 80s). As for Unix, in the olden days there were a lot of Unix variations (so there was a tendency to refer to ix as a generic term for all the variations) running on any platform that was at least 16-bit (I don’t think* there were ever any 8-bit Unix variations, but I could be wrong).

The first Leisure Suit Larry game was released 1987.

Huh, I was pretty sure that it was out while I was in high school so before 1986, but I guess that must have been some other adult video game paving the way for LSL.

Maybe you were thinking of Softporn Adventure from 1981. It's a text adventure game by Sierra (at the time they were called On-Line Systems), and Leisure Suit Larry 1 is a graphical adaption of it. Source Wikipedia.

Also, an 8088 cannot run Linux (but it can ran ELKS, which at least has "Linux" in the acronym), while there were a few Unices for 8086-class CPUs - with SCO Xenix being probably the most functional of them all.

Minix can.

Yes, but technically an Unix-like :)

There were a couple more, Coherent (also Unix-like) and PC/IX come to mind too

Neither. It’s a play on “Unix.”

LSL2 was released in 1988. The first Linux kernel release was in 1991 and required an 80386 or later.

So LSL2 came out in 1988, Linux in 1991, so definitely NOT a reference to Linux. However both the game and Linux are a reference to Unix (Bell Labs, released in 1970s). The LSL2 developers clearly knew about Unix. And the play on word "Eunuchs / Unix" is a reversal of the pun of the original Unix i.e. the authors of Unix were themselves making a pun on the word "Eunuchs". Here, what Unix was "castrating" was an even earlier (1960s?) operating system called Multics developed by Ken Thompson, who got frustrated by all the bloat and complexity, so sought to castrate down the complexity by writing the now famous Unix, whose paradigm spread far and wide and was re-implemented in Linux.
