I mean there is a need for some classic products to get reproduced because it's either something brand new that just plugs in and works, or fighting a 45 year old game console to make it work on a modern TV from Costco.
Traditionally though, I've seen a lot of these modern reproduction products are phoned-in schlock. There is the ability to make it something nice for the price they are going to sell it for (looking at you, 1-Up Arcade) but they cut corners and you end up with something that looks the part but really does not play the part.
I'll use for example the re-release Speak and Spell. Went 90% of the way, The LCD rather than a VFD is fine, it uses easier to source batteries in 2023 but opt instead to sample an entirely different synthesized voice rather than the classic TI chip, nullifying the nostalgia.
