I miss Star Wars Weekends style fun so much.
To an extent, I can agree, but there is a time and place for it. I think having Frank and Drac hanging around USF is the perfect place for campy crossover fun. Darkmoor itself is not.
I
would like to see Anakin, Luke, and Rey in Galaxy's Edge at the same time, but Anakin shouldn't be in sightline of Luke or Rey, and none of them should be dancing the Gangnam Style. At absolute most, Chewie or Stormtroopers could probably party it up in Tomorrowland. Galaxy's Edge simply has a different purpose.
I think the key aspect (for me) in the idea is that - No - the Scooby Gang doesn’t get “Darkmoor-ified.” It’s the instantly recognizable, bright-colored Scooby Gang within Darkmoor. The juxtaposition is part of the point (and fun).
Ultimately, for me, the key narrative draw of those characters in Darkmoor is “why wouldn’t they?” From my understanding of the world, Darkmoor is set in modern times in a village that just happens to have monsters. A Scooby story allows the village to get fleshed out by focusing on how the locals interact or feel about the monsters. I’m looking at “Abbott and Costello Meet…” and Scooby Doo! Frankencreepy as inspiration for this.
It’s unconventional, but it’s a way to attract and introduce kids to the Monsters in a far less intimidating way.
I can understand where you're coming from, and I think there is a version of it that could be pretty fun, but to me it still feels a little too "Donald's Dino Bash"-y to stomach as effectively an overlay to a richly detailed original world that opened up barely a year ago. I'd like to see Darkmoor live or die as its' own thing for a long time before we implement a single third-party IP, a la HTTYD or Madagascar in Lost Continent's final years.
In potentially more niche terms, I really wanted Mario Sunshine to crossover with Splatoon 1 back during the Nintendo Wii U years. It just felt like the perfect mix - summer vibes, shooting mechanics, icky paint-like goop. But in hindsight, I'm really glad they resisted the tempation to immediately add Mario to a new IP like that, because Splatoon's worldbuilding, aesthetic and vibe, and overall experience was given the chance to grow on its' own for over a decade now, and has firmly rooted itself as its' own thing, without expectation of "Well, what if they added Luigi too?". Splatoon is now an extremely healthy franchise that stands on its' own two legs.
I would like Darkmoor to exist without the expectation of being a big horror crossover land, which would unfortunately immediately happen if Scooby were brought in. "Well, what if they brought in Casper or the Ghostbusters too?". Let USF be the place where all that silly fun happens.
