It’s been revealed that famed developer Hideo Kojima managed to get Snake into Smash Bros purely because his son desperately wanted to see him in the game. Kojima’s son was disappointed that Snake wasn’t featured in the previous Smash Bros games, so Hideo Kojima had a word with Masahiro Sakurai to ask if he could include him in Smash Brother Brawl. Thankfully Sakurai thought that this was an excellent idea and included him.
“My child likes Super Smash Bros., so we play it a lot together. And he told me that there’s no character that you made in that game.”
“As you know, we did make Twin Snakes, but generally speaking, there hasn’t been a lot of Metal Gear on Nintendo platforms. So from that perspective, I thought it was a good way to expose younger people to this character, Snake,”
