Some Times you may want to add/adjust on your table
Fire Emblem: Radiant Dawn - 40hr average
Mega Man 9 - you have it at 91 hours. It can be beat in under 45 minutes. I would say it takes an average player 1 hour to beat it after they figure out the weaknesses. My first playthrough it probably took me 4-5 hours to figure out the weaknesses and make my way through.
Prince of Persia (2008) - ~10 hours, ~14hr for completion.
Professor Layton and the Diabolical Box - 10 hours average
Super Paper Mario - maybe I'm slow, but ~30 hours, plus I did the two pits.
Lunar Knights - 10 hours
Advance Wars: Dual Strike - 25 hours (I take a long time on maps)
Advance Wars: Days of Ruin - 25 hours (I take a long time on maps)
Trace Memory - 6 hours
