It's not so much that modern dev are not as capable, but modern console are much more malleable and offer much more power relatively speaking. Basically they're PC. The last console which required special tricks was the PS3, because the Cell was a weird ass architecture totally unsuited to mainly single core games, so devs had to do what they could to make it run well. When you look at old stuff, it's less "wow they were great to achieve that with such poor hardware" and more "I genuinely don't think it's possible to do that with the resources available ..." So they cheated. Or hacked. Whatever you want to call it.
The Saturn and PSX had some insane stuff. Go look at the tech specs of the PSX and tell me as a dev you think it's reasonnable to expect games like Metal Gear Solid, Crash Bandicoot, etc ... To run on that thing.
But still, the crown of "dev has to cheat around to do anything that wasn't 2d" remains with the Saturn, the best worst design ever for a console.
On PC we have few equivalent because our chips have always been very multi purpose, historically they were merely vastly underpowered compared to specialized hardware console had (which is why Carmack's 2d and 3d marvels in the early 90s were so impressive, getting an engine similar to keen or wolfenstein or doom isn't very hard, getting it to run fast on the hardware of the time ... Well there is a reason the guy's name is known the way it is).
War stories of developpers of that era are some of the best things to read as a non-dev game that enjoy reading about doing stuff you shouldn't be able to do. I remember reading such a thing about Panzer Dragoon II Zwei on the Saturn and it was so great, but apparently I didn't save the link and can't find it back.
