When Engadget unveiled its new and improved buyer's guides earlier this year, we started out with just a handful of categories: smartphones, tablets, laptops and wearables. You know, the stuff we're most likely to give the full review treatment. Still, a few of our readers wondered why we didn't include a wider range of products. To all you who were craving a little more, the answer is: We were already on it. Today we're adding two new guides to the mix, including one for gaming gear and another for portable audio gadgets. As always, when deciding what to include, we asked the people who know best: the Engadget writers who are already testing this stuff. In the case of gaming, that includes our resident game writers Ben Gilbert, Sean Buckley and Tim Seppala. Likewise, we consulted our biggest audiophiles on staff, Billy Steele and James Trew, who in a previous life wrote about music for a living. Have a peek at our gaming and audio guides, and check back over the coming months -- you never know when we'll add a hot new item to the list.
