It's not joke, It's "demand for demand". Some people tend to demand everywhere where demand is possible (and sometimes even where's not). You should get some clues from this, I think. There's one old sentence: "Still is no born anyone who content everyone". Remember that even God's son didn't do that!
For me people who demands this plays most times on UAE. Or they are collectors with opinion "It should run on (let's say) basic configurations or it's not count". Why? Because hardy one today have A500 with just 0.5MB, what I've said already. It's configuration which was obsolete already in 80's and everyone who wants to play everything what needs more than basic settings bought bigger RAM extension. And try to buy JUST 0.5MB of RAM today, almost impossible, everything's 1MB or more (not to mention powerful accelerators). So they're collectors with rare 0.5MB extension in use or they're lie for themself playing "basic settings" on... emulation.
Just saying.
Well said. Also there's the motivation for doing something that feels legit from the day, let's say it was released on the Amiga's heyday: it'd be probably an A500 game with similar specs as this.
I have an Amiga 500 with A501 expansion just like I had back then. Actually there's the fact that I wanted to see it running on "my Amiga". This wish is far from a joke, in fact (that was a bad choice of words.:)) Here's a photo of my A500 with some of my games:
