There aren't many games that have successfully followed on from Robotron - least of all the PS1 and N64 remakes.
However there are excellent games to be had - there's Bangai-O on N64 and Dreamcast, Geometry Wars on XBox and Wii, Smash TV on various (the SNES got an excellent port with NO slowdown and helped by the suitability of the controller), and Mutant Storm on PC(see pompomgames.com).
