How about playing Toriod Terror with Rack N Roll robots?
Let people modify their bots to do things that were allowed back then, like how about intentional tipping?
It's a relatively easy to build goal, small field and most teams probably have a robot currently build that can lift a tube. You could even use RnR tubes, it wouldn't make that big of a difference.
I know I won't be at Battlecry, but c'mon who actually wants to see 99 again??
And besides where would you even get a floppy?
