Few had the Dreamcast, fewer had the online network, )and if you fit into that tiny niche,) even fewer kept the internet service.
I fit into all those catagories. I had a Dreamcast. I paid to play Phantasy Star Online, and I did so for about 2 months then figured the price wasn't worth it. (And Phantasy Star Online was free to play unlike other MMO's so in a way you paid atound the same price as someone who has say a PS4 and a pay to play MMO.)
