The original rumble packs you plugged in were more powerful and they moved more weight, if I recall correctly compared to modern controllers. Would be cool to make a jacket or bodysuit + headset today you can wear that rumbles in the part of the body you got shot in

The N64 rumble pak also had a longer lever to the controller, making that greater weight even more felt.

The annoying thing, of course, was that you couldn't plug in a rumble pak and a memory card at the same time. There were third-party options available, but third-party memory cards had a bad reputation.

The Dreamcast solved this by having two slots. The VMUs were insanely cool at the time, and honestly still are. Some games used them in cool ways, such as Resident Evil showing your health.

I worked on a project that made a vest with controller vibration motors in it connected to a microcontroller. That microcontroller was connected by a serial -> USB converter and was controllable by the computer it was attached to.

Sadly, it wasn't for gaming. It was part of a study into the limitations of how much information humans can absorb at once, with the haptic feedback being tested as yet another input when there was a lot of auditory and visual input. I joked they should just use smell, but I don't think they wanted to subject the undergrad research subjects to weird smells.
