The creators of the Raiden series for thos of you who don't know. What other games did they do? Are they still alive? Any help would be mucho appreciated.
Here's a nice overview of Seibu's early games on the Next Level forums: Seibu
I agree with the posters there, Seibu is not dead yet, they're just dormant, but it seems the core dev team who worked on the Raiden series eventually split up. Perhaps some of them went to work for Moss, don't know about that, but it's quite likely.
