Would you like to relax? This game might be just the thing for you.
As one reviewer noted more eloquently than I:
The "feel" of Abzu is one of its best qualities. There's a sense of calmness and serenity that pervades every inch of Abzu. It's so refreshing to play a video game set in an underwater world and not be frightened of running out of air or be in a constant battle with the controls. Water levels in some iconic games are infamously terrible but Abzu is the exception. Most of Abzu is a different type of experience from most mainstream gaming but that's rather welcome. 2018 has seen so many monstrous-sized triple AAA releases that are full of open worlds with almost too many things to do. It's a perfect change of pace to literally dive in Abzu and just start leisurely exploring.
