All the coasts, mountains and ancient cities of the Nightfall (a standalone expansion for Guild Wars) are washed with a tinge of African and Arabian influences. Anyhow, cultural and folkloric inspirations aside, the game boasts of a whopping 15,000 sq miles of open-world that is almost double the size of countries like Israel! And this time around, bigger actually meant better, with the Nightfall gaining the attentions of critics and players alike – mostly for its open-ended nature along with adept instancing and excellent script-writing.
