Play games with my mom, i have a few memories from childhood with her
Playing Super Mario Bros. she makes it to world 7-2 while i'm stuck in 4-1 (we call that level Spiny-hiney world,lol)
Dad" *watching her* drop between the cheep-cheep and the blooper
Mom: *drops down and lands on the blooper and turns to my dad* see see see me drop!
Dad: i said between them not on the blooper
Me: *bursts into laughter*
Playing The Sims with my friend who has passed away back in 2004 we had to males living in the same house as a female...the two males ended up falling in love and they kissed my friend goes "Dude they kissed!" i miss him so much, i also played GTA with him and crashed into a building making him laugh and ask me were i learned to drive, my answers was "At Sears" lol
Playing Mario Kart with my mom and watching her fall off the road then Wario follows her off me to my mom "I think he likes you" her response was "Yeah well he can stay down there" since she was put back on the track first.
Also playing Dragonball Z Boudikai with my friend's brother, it was after his death when me and his brother were playing, we were laughing and carrying on and i hit a button combo and fried him with a Kamehameha and he goes "so that's how you do it" as he couldn't figure it out,lol i was using Goku and he had Vegeta and was messing around when i nailed him. we both said at the same time "i bet he'd be proud of that one"
those are some of my best memories from playing video games, i know you said childhood but i had to share some of them from when best friend was alive.
