Yes it's true they never recover from the time when the PlayStation came out but still they didn't change themselves when the industry move forward, third parties change, not Nintendo. Games like Street Fighter II, Mortal Kombat, Doom, Metal Gear, Shinobi, Final Fight, etc., aren't any better than what their original version were.
Wed 1st Aug Yes NES and Super NES had more third party titles, it still doesn't take away from the fact that they also had inferior ports like the Switch.Nintendo has been doing the same thing they were known to do since the NES days, maybe your time with them is over and you see a different perspective of them now because you change and they did not change with you cause securing Mature rated games they still do today (Madworld, Bayonetta, Fatal Frame, Shin Megami Tensei, No More Heroes, etc.), also supporting the same franchise year after year? Well if it helps them sell and make million then of course that's what they do, there's a reason they never revisit the Ice Climber and Star Tropics, one it could be that one is a shallow game and two it could be that the story for the other is already over and three it could be that the creator of those games move on to something else or retired entirely there's not much of continuing anything with them if Nintendo or the original creator doesn't see the potential in resurrecting them. Wed 1st Aug You mention that they are not the same company yet you failed to find evidence to prove your point.
