on the dreamcast? care to mention a few? im pretty sure most dreamcast games were released on other consoles at some point in time.
i know crazy taxi was released onto other consoles after dreamcast failed, i genuinely believe it didnt have good exclusives, maybe 1 or 2 but not enough to keep the console alive, it came too late, sony had already took over
What Nokkon listed above, but tbh I'd buy a Dreamcast purely for Shenmue.
I was always a bit of a SEGA and SNK fanboy though so I'm biased.
