Déjà vu can be a pain. Times when you're sure you've seen or heard something already. These moments, usually magic and mysterious, in arts - from cinema to music and, of course, in games - are generally considered negative. Déjà vu in these cases takes on its literal meaning: already seen, old, stale, repetitious. But sometimes, this french word can be a positive, giving sense to some aspects once insignificant.
