Although I'm fine if you refer to a page as a specific name and not as the digit (I even did this once,) please do not name a page "Level ___ - the ____ ___ ___." The digit alone is enough, and you can put the title in a Displaytitle template.
IG you have a point, but I don't know. I rather have the title of the level revealed to let people know what they are dealing with, or have a rough idea of what the level is about.
Cyrix, perhaps instead of making infactual statements to guard your subjective point, actually research the topic and realize that there IS indeed a {{DISPLAYTITLE}} template?
