LAS VEGAS -- New smart HDTVs may have hogged the spotlight at the International Consumer Electronics Show here this year, but the video-game industry had its own dedicated zone on the show floor.

In terms of video-game industry news, CES doesn’t compare with the Electronic Entertainment Expo -- set for the Los Angeles Convention Center June 11-13 -- but the annual technology conference did set the stage for trends we may see this year and beyond.

Cloud gaming appeared to dominate 2013’s CES, as graphics-card manufacturer Nvidia Corp. (NASDAQ:NVDA) spearheaded this movement with its portable and virtual gaming platforms. The company showcased its brand-new handheld gaming console: Project Shield. Powered by its recently introduced Tegra 4 processor, Nvidia’s Project Shield features a 5-inch touch screen attached to a traditional video-game controller. It runs on Android Jelly Bean, and players have access to any game in the Google Play store, as well as games on any personal computer running on Nvidia’s GeForce GTX 650 graphics processor unit.

Privately held gaming-laptop manufacturer Razer USA Ltd. also had a presence on the show floor to flaunt its PC gaming tablet known as Edge. The Windows 8-based PC has the ability to run most PC games, but with a new mobile flavor. It’s also designed to run Steam and allows players to connect it to a TV screen via Steam’s Big Picture feature.

Nvidia and Razer may have garnered a significant amount of attention on the show floor, but they were just two of the many video-game companies featured at CES. From cloud gaming of the future to putting a new spin on retro favorites, here’s the best of gaming at CES.
