I'd love to make a killer one in RCT2

Same though

I personally like think that including rct games with all that CS would be a bit unfair.

That's disappointing But whatever, I still have NoLimits 2

Maybe I'll have Rct2 or Rct3 contest next.

I have nolimits 2 but I suck at it

Can it be submitted in the form of a video with pictures or does it actually have to be downloadable?

Um... It has to be downloadable, but you can have a video too if you want. Just use the upload attachment feature in the post.
