The games Command & Conquer: Red Alert, by Westwood, and its sequel Command & Conquer: Red Alert 2, by EA, are both quite culturally influential on the board. Running jokes and tie-ins are often based on them, in particular by such members as LordInsane, alt_historian, euio, and Thande.
Einstein: Time vill tell. Zooner or later, time vill tell.
Kane: The foreseeable future…? Comrade Chairman, I AM the future!
Romanov: Hwe Rrromanovs have ourrr legacy to considerrr!
Dugan: I don't give a wooden nickel about your legacy! You call them off!
Romanov: The little turrrtle sees BIG RRRUSSIAN MISSILES, and he ducks! And he coverrrs… duck, coverrr, Hahaha! Today we will make historrry, Comrrrade Generrral! Togetherrr we will destrrroy the Unyiyted States; theirrr cities, theirrr homes, theirrr dreams, and perrrhaps more!
Less frequently mentioned is the other C&C game continuity (insert rant by LordInsane here about how they should actually be one continuity, and were before EA poked their abnormally large noses into the whole business), the Tiberian (and not 'Tiberium', adds LordInsane in an addendum to the previous rant, pointing out that EA has no understanding of Latinate adjectives) series of games. These consist of Tiberian Dawn (aka 'Command and Conquer'), Tiberian Sun,“Tiberium” Wars, which should really have been called Tiberian Twilight, and Tiberian Twilight, which was in fact called Tiberian Twilight.
