Hey, thanks for reaching out!
Yes and no. Nightmares of the Moon is a sandbox/RPG including the usual mini-games/systems that will give content depending on your actions and stat-management. Aside from the sandbox events, a lot of more narrative driven events are planned depending on your choices only. (Usual AVN style.)
Although the game will definitly lean toward corruption/slow burn content.
The game is out in a couple of days, you are always invited to try it out for yourself as the game offers a uniquely narrative driven experience :)
