completionist

/kəmˌpliːʃəˈnɪst/

Common

A player who tries to do everything in a game, not just finish the main story.

Can be self-deprecating or a badge of pride. Some completionists acknowledge the obsession is irrational but enjoy it anyway. The term also applies outside gaming to people who must finish everything they start.
