Attention wannabe Guitar Gods: you can now buy Rocksmith 2014 Edition for just £27.95 on Xbox One, including the Real Tone Cable.
It's a great price for a game that genuinely teaches you how to play guitar to various levels of proficiency, plugging your own axe into your console to become a real guitar hero. Thanks again, uwantsum!
However, there's a serious caveat that you need to be aware of. You will encounter crippling lag if you use an HDMI audio connection instead of an optical connection. If you don't use optical audio, we'd suggest staying well clear. Get the details in Carl's Rocksmith 2014 review.
