Whenever I see those shelves in department stores with the cheapie arcade products like Arcade 1UP or the Jakks stuff, I just roll my eyes, sigh, and let a little piece of my soul die away.
I don't care for making this hobby more accessible. I say keep it exclusive, niche. Makes people really work to learn about their projects, gets them to understand how to maintain their cabinets and it keeps the level of quality higher.
All this hoo-ra for making arcade games more accessible is just biting us in the ass. We've seen it already, time and time again, and it's getting worse. Prices of items are now getting to ridiculous levels. There was a list of sub-$100 boards that you could get a year ago (and was priced like that for years prior) that have now almost doubled in price now. This trend of converted original cabinets with ---smurfy--- raspberry Pi installations going for thousands of dollars needs to stop. Or we see people parting out original cabinets for these pandoras/pi's/60-n-1 and trying to hawk those parts for insane prices, as if they struck gold.
