Ok so i thought i would try guild wars with some christmas money i have however when i got to the store there was three guild wars and all were $50 Nightfall, Factions, and the reg guild wars. I dont really understand what is going on. I know they are expansions but a price tag of $50 for each seems a bit steep. So i was wondering if i bought one of the expansions does it also have the orginal game with it or would i have to spend $100 to have an expansion and the game? Any help would be great thx!
