Any obvious problems?

• Your slider buttons don’t have the pointer cursor, so you’re not letting the user know it’s interactive/ press-able.
• The navigation’s drop-down menus take longer, in my preference, to disappear than necessary.
• You could add a site description near the top somewhere, as I know it’s a gaming website but what type; e-commerce, review, etc. ?
• Your slider images don’t have alt values, nor do the slider-navigating thumbnails.
• With long pages like this guide you could add a back to top feature, where on-click the user is sent back to the top of the page.
• Your comment form goes to another page for validation errors, this makes it a lengthy process to post a comment and can be frustrating going back and forth. You could instead use a form that has validation errors on the same page of the form.
• Your Home page is not W3C valid https://validator.w3.org/check?uri=http%3A%2F%2Fwww.casually-addicted.net%2F&charset=%28detect+automatically%29&doctype=Inline&group=0 .
• Also check other pages for validity.

Thanks for your comments I will be sure to look into these!
