FWIW Dept.: Career points per game is actually one statistic in which Gretzky does not enjoy incredible domination. He's only slightly ahead of Mario Lemieux, 1.921 vs. 1.883. Moreover, Gretzky is in first place only because Lemieux staged a comeback after three years of injury-based retirement. Lemieux's career PPG after his first retirement, in 1997, was 2.005 -- ahead of Gretzky's career figure. Coming back to the sport when he was old and lame (literally) pushed Lemieux down a bit. Still, Lemieux's PPG for his final five seasons, in which he played only 229 games due to various health problems, was 1.347. That subpar stretch alone would be No. 5 on the all-time NHL career PPG list! Old man Lemieux's decrepit years are ahead of Sidney Crosby's career in this regard.
It's also worth noting that Gretzky is ranked only No. 7 in career goals per game.
