What if...

I'm not thinking one-for-one. I just wouldn't be surprised by an improved version of a game. And I can think of numerous ways they could redo AA without teams being able to reuse last year's robot design:

-add the end game
-smaller or larger balls
-shoot non-ball objects (spun inner tubes?)
-play on a field with 1/20 rise/run slope to the center of the field
-change frame perimeter

et cetera.

I like the mashup idea, or a replay of a game >4 years old, so current students wouldn't have any experience.
