I have not play Darksiders 3 or genesis , so I have no opinion.
’But I enjoy Darksiders 1 and 2. But I like 2 better because it is almost perfect game for me. I got loot system, can build your weapon with critcal chance and critical damage, you can play character as Death, can ride the horse any time in other world, many fun bosses, action rpg gameplay , you can choose skills, dungeons are fun and it not too hard or too easy, etc.
Also I remember the trailer bring the hype although I dislike giant guardian boss battle due trying to shoot big yellow ball.
