Name a game that's more then four years old that derserves a sequel?

[r4in]

The Guardian Legend
Cobra Triangle
Wizards and Warriors
Uniracers
Wetrix

(I strongly agree with Blast Corps as well. That game rocked all around.)

P.S. A well put together R.C. Pro-Am or Paperboy would rock. But they would have to harken back to the original in terms of ejoyability and sense of fun. Retain what made them great, kind of like what they are doing with Punch-Out.
