I'm not sure if I'm agreeing with you or not. But Wolf3D, Doom 1/2, and Quake all required top of the line PCs at the time. These games didn't run on anything considered average back then. These games in particular DROVE the industry to release faster chips. When Doom was released, most people had a 386, and it would run, in a tiny frame. But those who owned 486s, they could play it reasonably fine. When Doom 2 came out, it would play "okay" on a 486/33 but it really shined on a 486/66 which was out of reach for most people, and certainly out of reach for the 386 users. I remember saving forever to finally get a 486 dx4 100mhz and it played Doom 2 and Descent as awesome as you could expect. It was top of the line. The very first Pentiums were just being introduced.
Then Quake alpha came out. You needed a Pentium. The DX 4 100 couldn't play it for crap. Soon after the 3D card market exploded, again, thanks in part to iD Software.
So, seeing a game such as Batman wanting top of the line might not be ordinary today, but back then, every big game demanded it.
