I played it, it blows
Godawful combat, and stealth is unmanageable (it's nearly impossible to know whether you can be seen or not) and very little sense of direction.
Not that I want my hand held but everything about the world is so vague and obtuse and it just feels unearned. There's no gravitas to the mystery, it was just mysterious for the sake of having an answer(s?) to propel yourself towards.
Not much personality, no characters worth caring about, nada. Maybe it's just not my cup of tea, but I played it for two hours and really didn't dig it.
A very beautiful world to walk around in for about an hour, but that's all I really got out of it.
