I often thought about a additional device to handle G-forces for the player.
Something like an addductor training device which is posed between your knees and has to be pressed to keep grey or black out away. It stresses the whole lower belly and inner shank muscles and it would induce battle fatigue on a very natural way and gives advantage to the user with much experiance because of the training effect that comes along with excessive use
The design should enable pedal use and can be adjusted to personal preferences.
For those online players who dont use that device blackout occurs at an average level and those who use it can experience faster blackout or if trained way delayed effects.
