Kheldon tips an interview with Petroglyph's Chuck Kroegel about an upcoming MMO called Mytheon, which will be free to play, but also involve micro-transactions. It's an action strategy game with RTS and RPG elements. He says, "The game starts in the Greco-Roman era, as well as Egypt, and as time goes on we'll expand throughout the whole world. Something everyone has in common is they all have their mythologies, these beasts and these stories that have come to us through legends and folklore. All the nations of the world, they all have their own. So in our game Mytheon, we can eventually fill the Earth in terms of being able to explore mythologies of all nations. It's an action/strategy game, with elements of RPG, and elements of RTS that people have to come to appreciate and enjoy."
Update — 4/30 at 17:30 by SS: The summary originally linked to an article stating that Petroglyph was working with Trion World Network on Mytheon. This is not the case; they are working together on a different game, which is the MMORTS previously referenced in the title.
