Four years ago, Erick Cleckner was sitting next to his friend, Dave Chenell, in a class at Syracuse University. But they weren't exactly paying attention.
"[We were] just drawing in our notebooks instead of taking notes," remembers Cleckner. "And we were arguing about whose drawing would win a fight."
Their debate about whose character would triumph didn't end when class was dismissed. Cleckner and Chenell started working on a digital battlefield where their sketches could actually engage in battle.
