I mean if you go in YouTube and watch the reviews there is a pretty consistent sentiment from many players that the Veilguard is not a good game. The dialogue writing comes across as stilted, preachy, unlikeable, and often just nonsensical, with many of the character interactions being plagued with poor direction, lack luster voice acting, and odd pacing.
Couple this with the absence of meaningful choices for players to make that impact not only the character development but also the story, strange retcons that don't really improve things or provide any justification for the changes, and you've got enough problems to sink the ship.
Add on top of all of that the massive changes to the way the game actually plays, changes which are mostly simplifications that remove depth and strategy (actually tactical, but most confuse those words) from the combat, and being now the third bad game in a row from a formerly respected studio, published by a company that has very little goodwill or trust from gamers at large and it's not hard to understand why they missed sales targets by 50%. This article continued of to gas up a bad offering as good, I'm sure will contribute to EA continuing to fail to learn anything useful from this failure.
