Runescape is an incredible game, and the developer, Jagex Ltd., work day & night to provide players with the ultimate game experience (and have won many major awards for this).
Runescape is 100% safe. There are entire teams at Jagex that are working 24/7 to keep Runescape, the website and the Official Forums safe and suitable for all ages. There are many chat filters in place to keep everyone safe and sound, and many Rules and Guidelines that help everyone stay safe online.
Runescape receives updates and additions almost daily, which add to and improve this already massive game. With over 15,000 hours of free gameplay alone, Runescape will never become boring or repetitive.
Runescape is the best game I have ever played, and Jagex offer the best customer service I have ever experienced. It is completely free to create an account, so join the Runescape Community today! ^_^
I love this game so much, and I can't wait until the new Skill!!! I've been playing it for 10 years... And it's 11 years old, including RuneScape Classic.
Don't click the ads! JaGex does not guarantee your safety when it comes to those ads. At least, I don't think they guarantee it. I wouldn't, if I were them.
I have to disagree with you Security_Wiz. I'm a moderator on Runescape, which means I watch out for scammers and spammers on the game. It's a time consuming but good job. Anyway, Runescape uses a VERY powerful hack shield, so it's nearly impossible to break in. The software is updated constantly. You should be able to feel safe on Runescape, just don't click the ads.
