Last game I finished was Ristar... on the hardest difficulty (Super) by the way.

Funny story: Ristar came out for the SEGA Genesis in both the US & Japan on February 17th, 1995. I was born 10 years later on Ristar's 10th anniversary. Funny how things come full circle with the game I was born on the 10th anniversary of also being the last game I finished.
