Something X-Men '97 seems to get (and maybe I'll be proven wrong in the future, especially considering the show's success may have activated the C-Suite's brainworms) is the lost art of Fun Cameos being Fun Cameos and not what the MCU ultimately turned cameos into.
Captain America and Dr. Doom showing up in the middle of an episode as being tangentially involved with the plot doesn't indicate WE'RE GETTING CAPTAIN AMERICA '97 AND FANTASTIC FOUR '98, WHICH WILL BUILD UP TO AVENGERS '99 FOLLOWED BY AVENGERS VS. X-MEN 2000, it's just "Oh shit! Dr. Doom!" and then we move along.
