Somebody refresh my memory... does it matter if you've finished it 100 times or not?
Previously finished that I have finished in 2010:
1: Final Fantasy VI (SNES) - all characters... I had finished it at the end of 2009, but I absolutely had to have the complete ending, and to shave several hours off my previous time.
2: Adventures in the Magic Kingdom (NES) - This is one I've finished many times, but I struggled with it last night... fortunately, it's easy to never ever run out of lives.
3: Mega Man 3 (NES) - Again, I've finished this many times.
Finished for the first time in 2010:
Joe and Mac (SNES) - Normal mode (anyone know if hard mode provides a different ending?) - Fighting the last guy for a long time, and I get knocked down to my last life and last heart, and almost in full panic mode (and plenty of cursing), I pull it off.
