Sonic

[Who]

Guess what the second best-selling game series of all time is?

Hint: I play it and you don't

Hint: It starts with P and is better than sonic

Hint: It's an abbreviation of pocket monsters

Hint: It's Pokemon

Yeah, but Pokemon doesn't have a story, it's just capturing monsters, using them in a duel and win.
Sonic has been here longer than Pokemon. Sonic characters have depth. Sonic wins.

1- Pokemon is older than Sonic
2- It has a story, but if you are going to think of it that way then we could say Sonic is just jumping over monster heads.
