Ar Tonelico Qoga (AR3) Cosmosphere calendar set includes AR3 premium box and a calendar for a total cost of $69.99 so the calendar is worth about $10 which I think it’s a pretty good price for a calendar and it’s a rare item. The premium box itself contains AR3: Knell of Ar Ciel for PS3, an art book and official OST CD. Even without the calendar, the premium box is well worth it considering how much PS3 games cost these days ranging from $59.99 to $69.99 for new games. Most of the time, there’s no extra items come with the game itself.
Finally, will the game worth the price tag considering AR1 was a pretty big success and AR2 was somewhat a flop or so I heard ? For those, who has started the game, what do you think ? is it better than the first two games ? Check what other people says about the game on NIS America official forum before you decide to buy the game.
