I wonder if there is a world record for longest 3DO controller chain.

[A.C. Sativa]

Sure the max the 3DO system can use is 8 but that doesn't mean you can't keep chaining them after the 8th cotroller so if someone used all the 3DO controllers in the world how long would the chain be?

Given the small amount of 3DOs that were sold, probably not long at all.
