If all of this sounds overly harsh it isn't actually meant to be. The game is a mostly stress-free trip to Ancient Greece and one which incorporates numerable characters from Greek mythology in new and sometimes interesting ways. The graphics are fun, there are lots of mini-games which can be used as power boosts for certain attacks, and stylus use is both well-integrated and wholly possible to ignore (save for the mini-games) if you don't particularly enjoy it.
In the end, to some extent, you will get out of Glory of Heracles what you put into it. The story may operate all-too-linearly, but there are decent amounts of customization available for weapons and armor, and consequently a myriad of ways to outfit your party and outwit your enemy. If you're looking for massive open-ended play Glory of Heracles won't fit the bill, but it has a certain charm that makes it enjoyable despite any other shortcomings.
Glory of Heracles is rated E10+ (Everyone 10 and older) by the ESRB for Alcohol Reference, Animated Blood, Fantasy Violence, Mild Language, and Mild Suggestive Themes
