This is the first time Dreamcast owners can play it in a more understandable way (and I don't understand why some users are boycotting the translation due to the AI used in the translation work, but that's beside the point). Playing SGGG, we can all see how brave Sega was at the time. I'm still shocked that Sony had such good marketing around the PS2 launch, so users could trust them to wait - and NOT buy - a Dreamca…
The reason the PS2 was successful it was because it was very easy to unblock it and use pirated games. The Dreamcast wasn't as easy as I can remember.
Not to say that easy piracy is necessarily a death sentence for a console, the DS succeeded in spite of ubiquitous and cheap flashcarts, but the Dreamcast shows it's not necessarily a path to success either. There are just more pertinent reasons for a system to sink or swim.
