Your first mistake was assuming D&B was an actual Arcade.
Quick rant. So what's sad is the first Canadian D&B I ever visited a decade ago wasn't anything like the flaccid wasteland it is now, it wasn't actually bad at all. It was pretty evenly divided into half ticket-based amusements and half classic cabinets - proper golden age games, versus fighters, solid sports games, plenty of cabs I'd want in a dedicated arcade if I built one. Plus plenty of well-maintained pool tables and a bar with good service.
Recently they opened this giant one much closer to where I live, and my friends and I were stoked to check it out. Of course it was absolutely miserable: Rows of tepid rail shooters tied to whatever license, cellphone games you'd play on the can now in full-sized cabinets with one-button inputs, flavorless driving games that looked and played like a C-tier Playstation 2 effort. All of us left with cards nearly full of our initial credit purchases.
What really took the experience from flat to dreadful was that my two very young nephews came along for about an hour, and by the tail end of it they were both just completely bored, despite being attacked from all angles by sounds and lights. I remember watching my eldest nephew's face light up like it was Christmas morning when he spotted a Transformers enclosure cabinet, he was so hyped that him and I were going to play this thing. Literally bouncing up and down with a huge grin on his face. We played maybe two credits worth of this soggy, sleepy, utterly brainless rail shooter and he looks at me, just bored to ---steaming pile of meadow muffin---, and says let's play something else. I look around and that's the face of every younger person who's there to hang out but hasn't hit drinking age - most aren't even playing anything, they're just standing around, looking tired.
No classics, no versus fighters, no sports games, no pool tables, nothing that could inspire a lively competitive atmosphere of any kind. Even the Skee-Ball machines were these compressed-size space-saver deals that felt silly to play. It's like everything about the experience was tailored to be as lukewarm and shallow as they could get away with. And that was my nephew's first impression of a 'proper' arcade.
