Guild Wars 1 is now a very old game. At the time of writing, it is almost 10 years old. The game is split into four different game works: prophecies, factions, nightfall and then the expansion Eye of the north. However, ArenaNet have not changed the price for the game on the website for many years. As such, it is recommended that it is purchased on a different site and it is much cheaper. You will need to purchase the three main games and then you will need to purchase the expansion pack.
