For many of us, whether we consider ourselves gamers or not, this is more often than not the new digital battleground. And E3, though not overflowing with mobile titles, certainly has its share of the next potentially addictive time killers. Adam Balkin reports.

Motley Blocks could be one of the leading candidates for addictive time killers.

“It's kind of like connect the dots only it's connect the blocks, basically you start by trying to make chains of little pixel pieces, and if you're able to do this in a certain amount of time it'll create a cool picture for you,” explained Bryant Green, Square Enix.

And app developers, eager to set themselves apart from the thousands of titles already within app stores, are constantly coming up with games that almost create entirely new genres. In The Act, you feel like you're watching a show but the lead character is in constant need of a little nudge from you. Just a simple swipe to the right or left, it has to be just right though, too much and you blow it for him, show some patience and it pays off.

“This is a complete interactive brand new 2D hand animated adventure game. The idea is you become this character and guide the relationships this character has throughout the game,” said Daniel Kraus, React Entertainment.

But in a place like this with all these hardcore gamers and giant screens, it can be tough for an app developer to get the recognition they're looking for, but that hasn't stopped some who say bigger isn't necessarily better.

“Over time, I think you're going to see more and more hardcore content come to mobile in the form of apps, but if you look at devices like iPads and Android tablets, the processing power is pretty significant you can actually meet XBox Live quality,” said Eros Resmini, GREE.

And remember, games that are apps are on devices we already carry everywhere and cost anywhere from free to just a few dollars. Suddenly, it makes sense why some mobile games could easily outsell the bigger, flashier console titles here that potentially cost anywhere from ten to 60 times more to purchase and play.
