Another weird dream: an online roleplaying game where parties of four players each try to synchronize their characters’ magic powers and/or kung fu with a 4×4 set of knobs. I was playing it with my Doepfer A-138m Matrix Mixer, and someone else on my team had a Midi Fighter Twister.
Each column of knobs corresponded to a character, and each row a different category of ability (e.g. fire/air/water/earth, or attack/evasion/deception/defense, etc.). Each player mainly had control over their own character, but the closer other players’ knobs in that same column are, the more effective the ability is. (Or in some cases, you’d want the other three players to set their knobs opposite yours — it was complicated.) For maximum effectiveness all four players had to vary their own settings to match the rhythm of the combat or puzzle, and all four players had to coordinate with each other to maintain a defense or to attack as one to exploit an opening, and so on. Trying to have all your knobs turned up all at once would tire your character, and uncoordinated movement would hinder your teammates. And of course the knob settings affected the music too.
It was fiendishly difficult, required a very well-coordinated team and lots of practice, would never catch on and I have no idea how all this could translate in real time to something less abstract in terms of movement and choice making. My subconscious mind is creative, but is not a great game designer.
