gamer regret
n.— «The dirty secret of gamers is that we wrestle with this dilemma all the time. We’re often gripped by what I call “gamer regret”—a sudden, horrifying sense of emptiness when we muse on all the other things we could have done with our game time.» —“Games Without Frontiers: Battle With ‘Gamer Regret’ Never Ceases” by Clive Thompson Wired Sept. 10, 2007.
