I personally haven’t played Horizon myself; but from what I saw if it, it doesn’t look poorly made; it just looks by the numbers. Over the shoulder “cinematic” open world game with that Sony trope of the protagonist telling you the solution to a puzzle upon seeing it.
If my impression is accurate I would compare it to Quake II or Blue Beetle, if you are already a fan of Sony’s style of games you’ll most likely love Horizon, if you don’t like that kind of game then there isn’t much Horizon can offer you.
