Nintendo is easy, interactivity. As forerunners of the entire thing, their games have stood the test of time but it was up to devs back then to make things work, over time, what Nintendo did better than anyone is come up with unique ways to play, from the power glove to the Switch 2's mouse. Each gen they have tried and added stuff to make playing games easy and fun. Powerglove. :P Gameboy was small, easy to pickup and play and batteries lasted 17years. N64 and GC had 4 player ports by default, GC was small and easily carried, Wii had motion so good everyone else tried to copy it. 3DS was the only 3D we ever had that worked (shame this didn't take off, still never experienced it, not counting VR). Wii U and it's 'switching'... the switch and it's ability to .... switch. :P
Sony, this is an easy one, sure people are saying dual sticks but i think that would have happened regardless but technology. Specially being a technology company they seem to want to push the technology in each console, CDs on PS1 not only helped devs fit games but it massively lowered costs. DVD allowed the same but also massively helped the movie industry for sure. PS3 had blu-ray and bluetooth and wireless. PS4 had recording and steaming tech and the PS5 has the dualsense, honestly an impressive bit of tech considering it's only £60.
Microsoft, now sadly this is harder. I guess if I'm going to say positive, it's online gaming. I think their push for it on Xbox helped push it forward as I'm not sure Sony or Nintendo would have had such a push if not, comes with a hit though, we now pay for our online gaming.
Hmm, pie.
