Sadly, I failed the Super Mario Mega Marathon of Madness. =(
I managed to get 35 stars on Mario 64 before I was too tired to continue. It was sometime around 1:30 - 2:00, I think. I fell asleep on the couch. I woke up around 2:30, and decided it was time to call it. *sigh*

I was waaay off on my prediction, though. The games clearly took more and more time to complete as I went along. Super Mario World *might* have taken me less time than Mario 3. I'll have to check. 

Let's see... the last of the pictures.
Here's the <a href="http://i44.photobucket.com/albums/f26/roymacIII/Mario%20Madness/GoldCastle.jpg">gold castle</a> I was talking about. I think gold must not be as rare in the Mushroom Kingdom as on Earth.
Oh no! <a href="http://i44.photobucket.com/albums/f26/roymacIII/Mario%20Madness/KingYoshi.jpg">The King has been transformed!</a>
For that, <a href="http://i44.photobucket.com/albums/f26/roymacIII/Mario%20Madness/Ludwigistoast.jpg">Ludwig  must be defeated.</a>
Shock of shocks, the <a href="http://i44.photobucket.com/albums/f26/roymacIII/Mario%20Madness/ThatkookyBowser.jpg">Princess has been kidnapped.</a> Yeah. Nobody saw <I>that</i> coming. Two words for you, Princess: Body Guards.
I considered a career in <a href="http://i44.photobucket.com/albums/f26/roymacIII/Mario%20Madness/Ridingatank.jpg">Koopa's army.</a> They make you supply your own armor, though. Screw that.
I'm knock, knock, knocking on <a href="http://i44.photobucket.com/albums/f26/roymacIII/Mario%20Madness/BowsersCastle.jpg">Bowser's Door.</a> Yeah. Yeah. Yeah yeah yeah.
Oh, that clever <a href="http://s44.photobucket.com/albums/f26/roymacIII/Mario%20Madness/?action=view&current=Princess.jpg">Princess.</a>
Next up was Super Mario World... but first, <a href="http://i44.photobucket.com/albums/f26/roymacIII/Mario%20Madness/Itsnotdelivery.jpg">Dinner.</a>
Dinner <a href="http://i44.photobucket.com/albums/f26/roymacIII/Mario%20Madness/Itdmostlygone.jpg">didn't last long.</a>
Onward, to <a href="http://i44.photobucket.com/albums/f26/roymacIII/Mario%20Madness/SuperMarioWorld.jpg">Super Mario World.</a>
I was a little tired to get many good shots. I did capture <a href="http://i44.photobucket.com/albums/f26/roymacIII/Mario%20Madness/KoopasDefeat.jpg">Bowser's defeat</a>, though.
Can the Princess <a href="http://i44.photobucket.com/albums/f26/roymacIII/Mario%20Madness/Inmorewaysthanone.jpg">see the future?</a>
Looks like it's <a href="http://i44.photobucket.com/albums/f26/roymacIII/Mario%20Madness/gameovermangameover.jpg">Game over, man.</a>
Koopa was nice enough to send <a href="http://i44.photobucket.com/albums/f26/roymacIII/Mario%20Madness/Bowsersfamily.jpg">a family photo</a>, though. Very nice family you've got there.
Next up, was the ill fated <a href="http://i44.photobucket.com/albums/f26/roymacIII/Mario%20Madness/EvenMariolookstired.jpg">Mario 64.</a> That's actually the title screen, I kid you not. I should have known I was doomed. Even Mario looks tired.
I was clearly <a href="http://i44.photobucket.com/albums/f26/roymacIII/Mario%20Madness/Losingsteam.jpg">losing steam</a> at this point.
Still, <a href="http://i44.photobucket.com/albums/f26/roymacIII/Mario%20Madness/Shebakedmeacake.jpg">Princess calls</a>, and it isn't an emergency? I'm there!
As it happens, <a href="http://i44.photobucket.com/albums/f26/roymacIII/Mario%20Madness/Mariosnores.jpg">Mario Snores.</a>

If I try this again, I'm going to need to prepare a little better. I didn't get much sleep the night before, and I didn't have any snacks or drinks on hand. I think that I'd need quite a bit of soda and snacks to pull this off. 
It might be better to do it as a relay, too. If I had other people, and we were taking turns beating levels, we might be able to help keep one another focused. 

Anyway, I think I had a pretty good run. That last leg is a bitch, though. The 3d games seem like they'd be the hardest part. I'll keep training, though. Maybe some day, I can complete a marathon. Nobody finishes the Boston marathon on the first try, right?
