This is still accessible from a Dreamcast if you have a working one! I did that at the beginning of this year. Requires either a broadband adapter or a DreamPi (that’s what I used). You might be able to use the built in modem if you have a landline, but I didn’t try that.
I’ve recently gotten hooked on the Yakuza series. The whole series goes on an aggressive sale pretty regularly on Steam. I’d recommend starting with Yakuza 0.
