I would say Atari but that’s just low-hanging fruit because it’s a generation I never really got to play as it was before my time. But I am starting to fall out of nostalgia for the NES which is held dearly in a lot of hearts of retro gamers and gamers that have enjoyed what that system had to offer for a few decades.
I know it had offered a lot of classics and gave so many games their start, most of which are still with us today like Final Fantasy for example.
The best guess I can give about why I don’t care as much about that generation is because it is very oversaturated when you start entering the world of retro gaming. For retro gaming I prefer SNES and Genesis, because I technically did start playing those when I was born and they were first released. So I have more favorability towards those than the NES and generations before and during it.
7th Generation of consoles (PS3, X360, Wii) was pretty meh. The Wii was cool for a time, but it soon became flooded with shovelware and finding a good game was a chore. The PS3 was lackluster at launch and only got its footing at the tail end of the generation. The X360 had very few exclusives because most of their stuff was available on Windows.
This was also a time when apparently every dev, publisher and their mom operated under the presumption that “brown filter = rEaLiSm”. That, and bloom. Lots and lots of bloom. Good riddance.
