Ever since I started building coasters using tips from the website (no sudden flat turns at highspeeds, bank your turns, don't have insane Gs), I've been able to build huge, fun-looking coasters that the guests love.
Of course I still get some where it looks like anyone would ride it, but then I get a huge intensity rating. Or, it's under 10, but nobody rides it, even with good entrance placement, a low price, and a 6 week coaster and park ad campaign. Bah.
