I have the game. It doesn't. The issues at launch such as AF being broken, incorrect snow deformation, crashes, and others were all fixed within a month.
And the negative reviews are because of the tons of microtransactions and the game feeling incomplete (lack of split-screen, xp boosts, and a grindy multiplayer). You can literally fucking see them in the review history. The game has 17K reviews, once again, about 10% of the reviews that are negative came out on the first day. A 30-second search through the first few days of reviews will tell you exactly why. Here they are since you're visibly too lazy to get proper context.
Steam scores are not review scores. Do you even play on PC? Or am I talking to another ignorant fanboy who doesn't even understand how the platform works?
But let's take this a step further. Why does HZD only have 74% Positive Reviews in the last 30 days when it historically was much higher? Here we can see that on the 5th of May (and a few days around that date), the game was hit by more negative reviews than usual.
But what happened around that time? Oh, yes! The Helldivers II fiasco. Players took to negatively review the game in protest.
Understand now or do I have to make it clearer? You thought you were cooking with Gears 5 but ended up owning yourself further. HZD no longer has issues on PC, they were almost all fixed. You clearly don't play the game on PC, so who are you to say whether the game still has issues or not? I played the game on Day 1 and gradually saw the fixes from GG and Virtuos rolled out to address the various issues.
