Lemmings (Clockwise: Amiga, Atari ST, Sega Genesis, DOS (VGA))

It was still better than PC on VGA!
It shows you what crap the Intel/IBM platform was. And this was known since the 70's which is why Wozniak went with the Motorola 6502 and not the Intel 8008.
I'm talking in general terms.
The Amiga was specifically suited for platform games like Lemmings - because it had custom chips designed for certain 2D effects.
Also, Lemmings was done by Psygnosis - a famous Amiga-centric English developer - and the PC version was a quick port.
VGA was superior because it had 256 colors - where Amiga only had 32. Amiga PAL resolution was slightly superior, though.
But the PC destroyed the Amiga when it came to vector graphics, because the Intel CPUs were much better suited for the math involved. This, coupled with Commodore's lazy resting-on-their-laurels approach to Amiga evolution, spelled doom for the Amiga, as games like Wolfenstein, Alone in the Dark, X-Wing and Ultima Underworld became popular.
Beyond that, around the same time that VGA became the norm on PC for gamers - the Sound Blaster card was introduced, which was also superior to the Amiga sound chipset - and since a hard-drive was standard on a PC (where it was a very expensive accessory on Amiga) - it meant that games could have digital sound effects and speech, which was too memory intensive for Amiga hardware, with few exceptions.
So, around ~1993 - Amiga lost the race.
By 1994, Doom had been released - and it being possibly the first truly mainstream computer game whilst the Amiga simply didn't have the hardware necessary for that kind of 3D graphics - meant that any hope for Amiga gaming being competitive was pretty much annihilated.
Which is very sad, because it really was way ahead of its time for the first few years of its lifetime.
