Is Guild Wars free to play?

Excuse me, could you please clarify if the game Guild Wars is available for free play? I've heard some rumors that it might be accessible without any initial cost, but I'm not entirely sure. Could you provide me with some insight into whether or not this is the case? Additionally, if it's not free, could you elaborate on the pricing structure and any potential in-game purchases that might be involved? Thank you for your time and assistance.
