Gretzky didn't stop there. He raved about the young talent in the NHL, including Pittsburgh Penguins captain Sidney Crosby, who he called the best player in hockey, and credited the next generation of players with making the League stronger than ever.
"What's changed is the players are better, they are just better athletes, they are bigger, stronger, they are faster, and that's a good thing," Gretzky said. "Twenty years from now, they are going to be better than they are today.
"It says a lot about our coaching in youth hockey, in Canada and the United States and worldwide. It's just a better game today, these guys are big and strong and agile and fast. I'm glad I played when I played."
Gretzky will be back on the ice on Oct. 22, when he takes part in the 2016 NHL Heritage Classic Alumni outdoor game between former players from the Oilers and Winnipeg Jets at Investors Group Field in Winnipeg. The next day, the Jets and Oilers will play the 2016 Tim Hortons NHL Heritage Classic. Gretzky warned he's not the same player who earned his famous nickname.
"I'm really 'The OK One' now, not even 'The Good One,'" Gretzky said. "We're looking forward to it. Hopefully it's not too cold in Winnipeg in October, but we're all looking forward to the game."
Gretzky is also looking forward to the opening of Rogers Place. Gretzky skated there on Sept. 9, and on Sunday said, "it's like nothing I've ever seen."
"I've been fortunate to travel around to different arenas. I've never seen anything like the new arena in Edmonton. It's so special, it's so unique, I think the people of Alberta, people of Edmonton, Canadians for that matter, are going to be so proud of this facility," Gretzky said. "It's something so unique, something I've never seen before."
In the course of his career, Gretzky played 1,487 NHL regular-season games and 208 Stanley Cup Playoff games, winning four championships with the Oilers. He also played for the Los Angeles Kings, St. Louis Blues and New York Rangers, and said he loved every minute of it. Gretzky retired in 1999.
"Everything I have in my life is because of hockey and the NHL, I never took it for granted and never take it for granted," he said. "I loved every part of hockey: practice, preparing, the games, the travel, the guys, there wasn't one thing about hockey I didn't love, I think you have to be that way.
"Sure, we all get tired, sometimes it's draining, but let me tell you something, I have everything I have because of the NHL."
Gretzky said none of it would have been possible if not for the love and support of his parents.
"We weren't a family that was rich with money, we were a family that was rich with love and companionship and support," Gretzky said. "That's what Canadian life is all about, you want to support your children and give them every opportunity in their life to do what they can do and be the best that they can be. And that's what my mom and dad did. They didn't do anything special or unique, they just gave us the opportunity."
