Rickochet Red Dead Redemption 2 is an open world, incredibly detailed, sprawling western. I played the first one and it was in the top five most engaging games I've ever played - felt like the world of the game was "alive." This new one (a prequel, so no need to play the first to enjoy this) is much bigger, and even more full of various encounters.
It's the kind of game where you can wander about and see what turns up if you want to, or follow the progress of the story and its exceptional voice actors.
