Today, people just want to revisit games they used to play and most don't care or want an original arcade cabinet. They are just too huge and heavy and play only one ancient game.
I used to be into arcade games in the late 90s to early 2000s but once I discovered emulation I realized I could have "one cab to rule them all". Prior to that I used to have a few JAMMA cabs that I would swap PCBs in and out of to minimize the # of arcade cabinets I had.
Sure, the original games look cool, but my epiphany came when stepping up to my mint, restored Ms Pac I completed and played a game. I was bored into the 2nd maze and wondered why I was taking up that much space for a boring game.
If I was still into arcade games, then I'd certainly consider getting one or two of these systems. They look cool, can move by yourself without help or a handcart and most importantly the gameplay is identical to an original arcade machine.
I don't get arcade collectors anymore - I used to get it back when an original arcade game was the only way to play the game. But don't get the guys who clamor for a $700 Burger Time game or whatever. And that's fine because why should I care?
