The Google Play Store is loaded with games. Without calling out any specifics, there are many that are not so good - and some that are really, really good. Everything from casual games to more in depth games such as Dead Trigger and Modern Combat 4: Zero Hour. But for the focus here, lets concentrate on the casual games. A few of the top developers in this realm include Imangi Studios, Rovio Mobile, Halfbrick Studios and Zepto Lab.
