Last Hudson game I played was "Elemental Gimmick Gear", for Dreamcast.  It's a very underrated action RPG.  It's very fun, and you can find it for a great price these days.
I've heard reports that NEC's "Tube Sliders" was supposed to be the next F-Zero game, but the deal went to SEGA instead for F-Zero GX/AX.  This is a good thing, in my opinion, because SEGA's work on F-Zero was absolutely AMAZING.  Not only that, it's totally loaded with awesome SEGA butt-rock music, and that's bonus points in itself.  Anyway...  I believe I also heard that the Tube Sliders team instead programmed F-Zero:  Maximum Velocity for the GBA;  A team by the name of NDCube.
