Now for the shameless plug... My game's protagonist is an Amiga fan and the Amiga has a little cameo in it: https://store.steampowered.com/app/3040110/Outsider/
Technology advanced much more rapidly in those days. Similar to how hard drive capacity seemed to double every six months for a while, or how there's a new bleeding edge AI model every three months today.
Also, VGA had 256 colors. The Amiga had 4,096 simultaneously.
Of course in 1987 a Macintosh II with a fully expanded "Toby" framebuffer could not only do 256 colours, it could do it in 640x480 mode where as a PS/2's VGA could only do 16 colours at that resolution. And an Amiga could only do flickervision at that res.
Of course with technology improving all the time, not having a updated chipset circa 1987 that at least had a progressive scan 640x480(ish) is one of those things that really killed the chances of Amiga as a serious computer. They only got that circa 1990, and "Super VGA" was already just about becoming a thing in the PC world (and Microsoft had kinda got round to making a version of Windows that didn't suck by then). I'm not sure if the mythical Ranger had a progressive mode, but it's it does show how Commodore inability to keep the custom chips updated in a timely mannner slowly sunk the system...
If cost is no issue, the PS/2 also had the 8514/A card that could do 256 colours at 1024x768. And there was also the PGC from 1984 that could do 256 colours at 640x480.
That's the highly special hold-and-modify mode (https://en.wikipedia.org/wiki/Hold-And-Modify). I tried pretty hard to word my comment fairly, remembering the sometimes legendary tenacity of Amiga fans. (Which nowadays includes yours truly.)
