Los Angeles, California (CNN) -- Playing high-profile video games quickly from portable devices such as your iPad might get easier after this week's Electronic Entertainment Expo.
While the E-3 "game changer" tag has been reserved largely for innovations such as 3-D and motion-sensor systems, several companies hope using cloud computing to store games will be the real shift by letting gamers play high-end titles anywhere, on almost any machine.
If fully realized, they say, cloud gaming could be a console killer.
Gaming company OnLive announced Tuesday that it will make 23 popular console games, including "Assassin's Creed II," "Batman: Arkham Asylum" and "Mass Effect 2," available through an online subscription service.
"Today we're taking the first step toward a future where video game content is increasingly free from the restrictions of device and location, while showcasing the ability to instantly play the latest, most advanced games at the touch of a button," said OnLive founder and CEO Steve Perlman.
