GameLengths

10 hours with all terminals, no limiters, and a lot of the tests at the beach.

It will took about 5 hours if you play it with all limiters and see the story.
Great game, i really liked the gameplay

Took me seven hours but at least one hour of that was sitting in the hammock on the beach. Man, that sky looks nice.

Took 12 Hours with around 6-10% limiter. Spent a lot of time in beach for creating different Weapon styles. Great game...

The game warrants a new game plus playthrough as abilities carry over and some story elements change.

Took 10~ hours playing through the story with minimal limiters (Abundance, Initiative, Concentration). Combat system gets even better once "new game+" is available.
