Along the same idea, in 2007 our robot had removeable carbon fiber ramps that we would use or remove depending on our alliance. If our alliance had a ramp bot, we would remove them for visibility and focus on scoring, if we didn't have a good ramp bot, we'd score and then lower the ramps and lift our partners.
It was a nice feature that we could add or remove on a match by match basis if needed.
On the topic, i've always imagined that an awesome game would include multiple game pieces of many shapes. Say inner tubes, balls, and tetras. Causing teams to either have to focus on one type, some kind of complex system to manage all 3, or modular systems for managing game pieces depending on your alliance partners. I thought this might be the year during kickoff when they kept showing all the old game pieces, but turns out that's not the case.
