I agree that the series CAN continue without him, I can agree that at some point it will happen and has to happen, but I will never agree with ''He's just a mascot!" ''HE GETS TOO MUCH CREDIT."
Nah, fam. He's the reason we have the biggest crossover in gaming history. He's the reason Kid Icarus got a revival. He's part of the reason why Fire Emblem was able to save itself. He brought Mega Man back to Capcom's attention. Helped Xenoblade's sales grow through including Shulk. Because of his attempts to add fan requests King K Rool is now most likely back to stay. He's the reason we see retro gaming characters like R.O.B., Ice Climbers, Duck Hunt, etc in a modern game when they could just be setting on a shelf.
I don't think some of you are thinking through just how much Sakurai has accomplished with Smash, even OUTSIDE of Smash.
