With smart phones growing more advanced and having a massive audience, mobile gaming has become more mainstream than console gaming. That said, mobile gaming is still young, and the quality of games the new casuals are experiencing are nothing when compared to something like The Last of Us, Ico, or Super Mario Galaxy.
Mobile games are already more than socially acceptable, and as smart phones grow more elaborate, the games they can handle will as well. Eventually the type of games real gamers play will become mainstream entertainment through the growth of mobile gaming. I'm sure I'm not alone in assuming that games would eventually be the largest form of entertainment, but I'd argue that because of the changes smart phones have put into motion, gaming will become the primary form of entertainment sooner than expected.
