I love arcade games so both DC and Saturn are perfect for my use, especially with my MODE upgrades. Saturn team just couldn’t pick a lane. I have a couple of DC Ethernet adapters but they don’t work with most games so the modem+dreampi is good enough for me.
You’re talking about modern gaming now the original servers are down. I used a DreamPi now too. But the DreamPi is a comparatively recent addition as well as being notoriously painful to set up for non-technical gamers (doubly so if you’ve got a PAL Dreamcast).
Whereas I was talking about gaming on the Dreamcast back when it was still supported by Sega.
I was referring to how most games never supported the broadband adapter. Compatibility list: https://segaretro.org/Broadband_Adapter. I'm old so I bought mine on launch day(s) both US & JP. BBA in 2000.
