Can s/e actually make a "dungeon"?

If we had a 1~2 hour dungeon, people would insta quit when they got it in the roulette. That being said I want a 1~2 hour dungeon

If a dungeon is engaging, challenging and fun I wouldn't notice I had been in there for 2hrs until after its over. I guess the hard part is making it like that.
