In a new interview with Polygon, Zeschuk says in his case it boiled down to a lack of passion. "I just wasn't as into it as I was originally," he said.
"Everything's a factor," Zeschuk continued. "There's nothing that's not a factor, but there's no single one thing. I think the best way I can describe is: Do the same thing for twenty years and it's very, very intense. It's very high pressure. It's very high stress. It's challenging. It's sometimes rewarding and sometimes it's not. And you just get tired of it after awhile. That is probably the easiest way to for me to describe it. Sometimes you just need to change things."
