I'm sure there's all sorts of opinions up in this thing, but it'll be too long and probably eye hurting in some cases to read.
Do I agree NO. Do it disagree either NO. Yeah that makes sense doesn't it? Truth be told, the industry thanks to the greed and stupidity of uncontrolled game development and developers the industry was fucked in 1983 hard as far as the non-Japanese market goes when it came to consoles. Nintendo had a few people with some pretty brassy balls try and bring things back with an overly iron fisted Yamauchi insanity going on tactics and all and in 1985 and into 1986 it brought back what had pretty much (handheld LCD toys and computer games aside) resurrected a dead industry outside of Japan where it was thriving. The NES did that. The NES also gave us many mainstays that stick with us even today. I'm talking about the solid 8 point comfortable d-pad, controller style in general, solid practical console bound light gun games, even DDR has something to nod to with the annoying power pad. Without the NES you likely would not have had Sega take the plunge with their Master System, and from there no Gameboy from Nintendo, Game Gear from Sega, NEC wouldn't have jumped in with the HuCard and CD based systems and so on.
Sony bless their icy hearts they didn't give a shit other than game development. Nintendo brought them in with their SNES sound chip, then some limited game development licenses too, but ultimately Nintendo fucked them in the ass hard with the SNES-CDROM device. We've seen it, literally, Ben Heck fixed that shit too, the Nintendo Playstation. That device having been looked at has the roots of what became the PSX with a lot of upgrades and changes to the device, and some not really so much too, it was a learning tool. Nintendo fucked them, they wasted a lot of money and time for nothing, so they ran with it and we got the PSX. Playstation now that thing was the single most important CD based console in history. It's also perhaps the single most important mainstream console in history too. As wide spread as the NES was it never really got keen with the 18 and up group, gaming even if for just the era to blame, was a kids/teens thing. Sony with the PSX they made it gaming for all ages. They also made much of their bank off what Nintendo fostered, a shit load of AAA quality franchises that were birthed on the NES and SNES, not on Sony's watch at all. Nintendo, the NES in particular was the most important system in general to gaming as it resurrected an caused it to flourish, but Sony with their PSX is the most important system to bring games into the mainstream, the masses, and of all ages making the older perception of just for kids with Nintendo and Sega start to become a fading memory.
