... online stores, anyway.
The arcade shooter Psyvariar 2: The Will to Fabricate was just released for the Dreamcast (evidently ithe arcade original runs on Naomi/Dreamcast hardware) with a PS2 port coming soon. I got my copy yesterday, and I am impressed. I would have played it more, but I went out drinking beer to celebrate the game's arrival by FedEx. Evidently it sold out in Japan. I'm sure they will do a re-release.
It's a very cool vertical shooter similar to Radiant Silvergun, Ikaruga, and the like. It features excellent graphics (2-D shmuping over 3-D graphics) and a cool scoring system where getting nicked by gunfire can rack up some SERIOUS points, though the game itself appears to be pretty short. Perhaps I should try in on a setting harder than limp-wristed wimp (or "monkey mode" in some Japanese games.) The game's designers certainly were in love with pyrotecnic fire/explosions effects, and the DC delivers. Slowdown is minimal except during the end of the boss battles where the screen just lights up... perhaps it's intentional.
Here's a link to NCSX....

I recommend picking it up as it may very well be the second-to-last shooter released for the DC (commercial software, that is.) JapanVideoGames may have it too, but their shipping prices suck ass. Both firms offer excellent service and pick up the damn phone when you call. NCSX especially.
