G-Force effects are now built in with the Game of the Year Edition. The field of view narrows, becomes blurred until a complete blackout/redout occurs and the aircraft is no longer controllable.
Under Assistance Options > User Experience you can choose accordingly whether:
- the G-Effect is off, as it would be for a trained pilot, or if the effect works as it would for an untrained civilian.
- whether one has put on an Anti-G-Suit or not
Accordingly are the effects then. Try the settings when flying with the EXTRA 330:
G-Effect: Civil Aviation Pilot
G-Suit: OFF
Have fun 
This is how I imagined it.
Positive G-Force (Blackout)
Negative G-Force (Redout)
Also you can now hear the press breathing in tight turns.
I did not test hypoxia and wake turbulence 
But I am very satisfied with the G-Force effects. Well done Asobo, many thanks!
