Video games for skills

Hi everyone,

My little brother ( 16 ) has "level 3" autism and has recently been diagnosed with moderate intellectual disability/delay. He loves car games and wants to go for his license soon but struggles to understand certain concepts, he also finds mathematics hard ( I still count on my fingers and mentally have to picture it so I don't blame him )

I was wondering if anyone knew of any games that could maybe assist him in life skills? If that's even a possibility. I thought Supermarket Simulator could be a good start and I'd sit with him and guide him through things. Or if there are any cooking games or, just games where you can have fun but still learn and grasp an understanding of things. As an older sister I'm just looking for a way he can have fun whilst still learning, we both love video games and I'm hoping maybe I can help him this way. Thankyou !
