Well for starters its not very replayable, nor does it have a lot of content as it's a linear RPG. Pretty much everyone who got it at release was done with it ages ago. Was also a bit of a let down in regards to awful level design, side quests and pace-killers making replaying it even more painful.
Honestly though, 2020 has quite a few of the biggest releases of the generation (Already has HL, Animal Crossing, FF7, TLOU, Tsushima soon, with Cyberpunk and all the next gen stuff still to come), so it's really not surprising that any one of them is gonna lose traction after a few months. Not to mention it's also a remake, so there wasn't a whole lot of new to talk about anyway.
