I like the fact that there are games that are still best played on the Dreamcast, or only played on the Dreamcast, since there was no follow-up console after it, or because the ports were not great. Today there's always a remaster, backwards compatibility with the next console, or at the very least a sequel, so games just move along with the hardware. But the Dreamcast had some games that just lived and died on that system.
Weirdly, most of these turned out to be fighting games. Probably because Capcom liked the Dreamcast.
My favorites that are still best (or only) played on that system:
Crazy Taxi (the ports don't have the original soundtrack, an absolute sin)
Power Stone and Power Stone 2
Marvel vs. Capcom 2 (literally one of the best fighting games ever, and it can't be purchased on any systems today)
For sure. Plus, I'm a sucker for fighting games where the characters are 2D sprites instead of 3D models. The DC probably had the best lineup for that, ever.
