What is Worlds of Fun like?

I know this sounds stupid..... But I've never been to W.O.F except for when I was like 4 to Camp Snoopy World. I've been on The Incredible Hulk roller coaster in Universal Studios and I really liked it, but my brother made me go, because I have/had rollercoaster fobia.. So after the ride I asked my brotherif that was anything compared to W.O.F and he said it was WORSE than any of the rollercoasters there. I actually really just want to know if any of the rides will make me really sick to my stomach?? Please nothing hurtful. Thanks!
