The Naomi and the Dreamcast share very similar game libraries. They were from the same generation. The Sega Dreamcast was the first console that finally was completely on par with the arcades, something the PS1 and the Saturn couldn't fully accomplish.
Interestingly enough, when the Sega Dreamcast went down, the arcade culture in the rest of the world outside of Japan also went down. It's like people thought that now they really didn't need the arcades. Then online gaming further down killed it.
Games like Marvel Vs. Capcom 2, The House Of The Dead 2, and Dance Dance Revolution were probably the last breath of that amazing era. The golden age of gaming in my opinion, that lasted all the way since Pong.
The Sega Naomi used to run on Net City cabinets, but sometimes people would still use older Blast City, Versus City, and even Astro City cabinets. Others will straight up use an Egret II.
Although around the area I grew up, pretty much all the cabinets were pedestal, similar to this SoulCalibur cabinet (also a Dreamcast exclusive):
Pedestal cabinets are the ones I identify arcade culture with because those are the kind of cabinets I grew up with. Ultimate Mortal Kombat 3, Killer Instinct, Mortal kombat 4, Killer Instinct 2, Tekken 3, Marvel Vs. Capcom 2 were all on pedestal cabinets.
In fact, the only upright cabinets I saw that weren't pedestal were the ones running Neo Geo games such as Aero Fighters 2 and Metal Slug. I never saw those small Mortal Kombat ones people collect now.
On-rail shooter arcade games like The House Of The Dead 2, Virtua Cop 2, and Time Crisis 2 all had big cabinets as well.
When the Sega Lindbergh and the Namco Noir hit, the arcade culture was already gone, not to mention when stuff like the Vewlix came out.
However I love how modern sitdown cabinets look. I would love to have one in my house. They are just ridiculously expensive to import.
