Microsoft’s 2013 E3 keynote is over, and like the company said back when it revealed the console last month, E3 will be all about the games. It was! Through the standard array of space marines and space armor, zombie apocalypses, and racing, we did see some new IP, as well as genres not usually associated with the Xbox platform, such as the brawler.Aside from the actual games, what did appear a few times was the Xbox One’s SmartGlass interactivity. It wasn’t shown off too much, but we did get a glimpse of how Microsoft plans on using it this coming generation.SmartGlass never seemed to be a true focus of the show, as its most in-depth showing took place during a demo for Killer Instinct, a game we all wanted to see up-close more than we wanted to see Microsoft’s second screen experience. So, while demonstrators were showing off SmartGlass, we were all paying attention to the over-the-top KI announcer that has been missing from our lives for the past 17 years. However, throughout the show, we did see two very distinct uses of SmartGlass… and they were a little underwhelming.During that Killer Instinct demo, we saw the demonstrators use SmartGlass to deal with the lobby functions of the game, as well as perform some basic Xbox Live tasks, like checking out achievements and leaderboards. There was also a Smart Match feature demoed, which allowed players to create something akin to a queue of multiplayer matches while they played in the single player campaign. SmartGlass was also used to invoke and record a Twitch.tv livestream.During the Dead Rising 3 demo, we saw the demonstrator use SmartGlass to call in an artillery strike to thin out a horde of zombies. Yes, you could most likely just use an in-game interface for that.If the keynote is any indication, SmartGlass will be something like a Nintendo-style gimmick — a decent idea, but more or less left up to the developers to be creative with if they want, rather than be forcefully implemented by Microsoft. The second screen experience, while viable for television and movies, may not work as seamlessly in the realm of gaming. The difference between the two worlds is that you’re somewhat passively watching television, whereas you’re actively playing a game — both of your hands occupied by a controller.It’s most likely safe to assume that we’ll see more of SmartGlass over the next few days during E3, but if Microsoft busted out its best uses for the platform during the keynote, SmartGlass won’t really change the way we game.
