Damn, posted in the wrong section. Oh well.
I was just thinking that if someone wanted to do a line or lines that they could, but each trick in the line would count as one of the five.
So like you could do 2 single tricks and a 3 trick line as an example. You could do one long 5 trick line. Whatever combination you can come up with that equals 5.

Oh yeah, not an original idea at all haha. SkateCC (is that name right? been a while) and LikeButterMag did 5n1s.
I would want to know if everyone had the Downloadable Content. That could be fun, don't think I've seen one in the DLCs yet.
