I'll give 4 stars. The game has bugs, yes, but you can still play, I went for like 2 to 3 hrs just doing story missions and I never got the error or the game to crash. The bug that causes the game to return to title screen is caused by a bug in the coding of the menus, if you go and click on for example a character and immediately tap on level up, and by immediately I mean not the moment you see the screen change, the game will prompt you the error message and send you back to title.

good game overall for me but its still has a bug because i know its beta,i hope the full release all will be better

Great game so far. Having played for a couple of hours I'll have to say great job from the developers. The environments are well done and there have been a lot of attention to seamless exploration. The short loading times are great and the option to disable auto right from the starting tutorial is just fantastic. The games dies fall short in the performance department due to the crowded servers and the lack of characters rendering and lag is a major problem at the moment. My device is past the recommended by a fair bit but the game can be described near unplayable around the starting town.
