As long as you're happy and comfortable getting what you want, why not? There are far worse things to be spending money and time on. I remember a bloke on here a while back and he had given up smoking in order to buy pcb's. He was convinced that pcbs were a great investment. Maybe they will be, maybe they won't, but far better than smoking!
I still play these games and I still get a kick out of it even if only for 15 minutes a go. Yes, even the likes of turtles and Simpsons.
Longer term, one factor I'd put into speculation is the potentially dramatic impact of a less physical world going forward. For many reasons, not all good, there is a push to own less and less, especially physically things. Rent this, rent that, "emulate" this thing, emulate that. All transient.
Much like how housing wasn't spared too much of a thought 30/40 years ago, now it's ridiculous to the point that the likes of grandparents find it very difficult to understand.
So, in the same vein, we might not appreciate the physical things around us so much now, but nothing screams physicality like a whopping gigantic arcade cabinet when compared to someone who's entire ownership of "stuff" can be put on a USB stick in the future. And they have a social element to them as well, again, something that's on the decline (pandemic not included).
That's my upside opinion on costs long-term. Equally, all arcade things could be relegated to worthless.
Bottom line, don't speculate too much and enjoy what you can within reason. I won't be spending 5k on an outrun, that's just me!
