Erin Slingsby, 20, ploughed into boyfriend Kane Charles as he stood in front of her car after she'd stormed out of his house in Doncaster after an argument over the video game.
Mr Charles, also 20, managed to drag himself to his feet, but as he staggered towards his home, Slingsby mowed him down a second time.
He collapsed and woke up in hospital with a fractured skull and bruising to his brain, Doncaster Crown Court was told.
Mr Charles, a plasterer, faces years of rehabilitation and suffers from memory loss, impaired concentration, mood swings, constant headaches, and dizzy spells which means he can no longer work.
Ian Goldsack, prosecuting, told the court the couple had been in a relationship for two years before the incident in 2009.
He said Mr Charles had followed her outside to give Slingsby her phone and had stood in front of the car to prevent her driving off, but the vehicle jerked forward, he fell back and hit his head on the road.
The court heard how despite feeling dizzy Mr Charles got up and started to walk back to his house but Slingsby turned the car around and he was hit for a second time.
Mr Goldsack added: ‘The next thing he knew he was waking up in hospital.’
Slingsby returned to the scene of the collision but denied any involvement and said Mr Charles had fallen or been hit by another car.
A year later she admitted to a friend and to her brother. That she was responsible. Slingsby, from Doncaster, pleaded guilty to dangerous driving.
She was sentenced to 11 months in a young offenders' institution.
Slingsby was also handed a two year restraining order banning her from making contact with Mr Charles and a three year driving ban.
Judge Jacqueline Davies said: ‘It was an extremely serious incident and has grave consequences for Mr Charles.
‘He suffered serious head injuries with almost certain long term implications.’[/p]
