Despite me not being a customer for it, these casual turn key solutions help more people get into the hobby and make it accessible - especially if these ever hit retail shelves and get plenty of eyes on them. A decent amount will want more after and learn about other options. Much like A1Up has brought more people in who've transitioned to original hardware or full size modded cabs. I think it's a good thing in general and creates more aftermarket options down the line as well for all of us.
IMHO, this is the optimistic view. It doesn't usually play out that way. After seeing how this site has declined since the introduction of the A1UP cabinets, where those "less than" offerings have taken on a life of their own, that is probably not the case. Many who are attracted to them actually think they are getting the full experience when they aren't. This pulls them into an alternative "sub-ecosystem" where it becomes about those particular units, rather than the more authentic experience. It's not always the case, but if that was happening overall, it would have caused a "boom" in sites like this one, and that hasn't been the case. As a result, we have a whole generation of players who think they have experienced something authentic, many of whom who have become disinterested due to shortcomings.
Poor experiences don't lead to more interest and are more likely to lead to abandonment. So if more engagement is what you are hoping for, one should probably hope that this offering provides solid performance at least marginally on-par with what the PS1 and a GunCon could offer with a CRT. Otherwise, it's likely to do more harm than good with regard to bringing new light-gun players into the fold, especially if it's only good enough to hold temporary interest or to be considered a nostalgic curiosity.
Blank white walls behind screens and disclaimers mentioning "casual experiences" are giving me a bit of cause for concern, but I'm waiting for the reviews to see how well it holds up. Maybe they have some tricks up their sleeve which aren't being shown yet.
