Seven in Common (1/24)

For this puzzle, consider a two part name as a single group with a single letter count. For example, STEPHEN KING could be read as a single group with 11 letters.

Now, I'm thinking of two individuals, one famous for creating graphic novels and the other famous for creating games. I won't reveal how many total letters are in their names, but I will say this: the first 7 letters of both complete names are exactly the same.

Who are they?
