The games at the bottom are kind of hard to see. They are (top to bottom): Wizards & Warrior III, WWF Wrestlemania Challenge, WWF Wrestlemania Steelcage Challenge, Yo! Noid
The cartridges that are stacked vertically on the third shelf are my "for trade" carts, and the boxed games below that are also my "for trade" titles. They're mostly sitting there to keep the incomplete shelf from falling over.
