This seems very legit, but I don't know if it's out or not. Сегодня DeNA выпустили free-to-play игру под названием Infinity Blade Cross. http://m.youtube.com/#/watch?v=LzVrYCPKfGI&desktop_uri=%2Fwatch%3Fv%3DLzVrYCPKfGI
This game was released and later closed in Japan. It was like the first IB, but instead of exploring there were some missions. It also used the gem system from IB2. If you already have IB or IB2, don't worry. You're not missing anything.
Mobage isn't that bad, look at FF airborne brigade, besides no sound it was pretty good and im sure FF tactics S will be good too.
