There's a lot of homebrew for pre-NES consoles which have 8/16-bit quality gameplay. Many new games are receiving huge carts, similar to Pier Solar and Project Y and new programmers are really pushing the hardware, alongside some talented pixelarts and chiptune composers.
Even if people have a problem with a lot of pre-8bit generation games, they're still missing out on a bunch of great games that they would enjoy.
