Yeah, vanilla is a nice flavor too.Monty Python and The Holy Grail is pretty much the most referenced source, despite it having been made before most of my players where born!
The other problem with Dune is it's brand of space magic is closely tied to the setting and very distinctive. Same is true of Star Wars. That's great for world building, but for something like Level Up something more generic (e.g. Traveller) is called for. Generic is boring, but it has the best chance of appealing to the broadest target audience.
For core rules, I want vanilla. High quality vanilla, with real vanilla beans. None of that artificial imitation vanilla that tastes weird. Maybe with an egg for French vanilla. Wholesome icecream goodness.
For psionics, this means, clean normal mechanics with personal power-of-mind flavor.
Let each setting add its own special toppings on the vanilla icecream, or neapolitan, or maybe even a whole pie.
Let experimental mechanics be something that can be added, not something that players get stuck with.
