Been playing Starfield for about 150 hours, I can say it has been a journey of mixed feelings. Here's what I think:

Quests: Starfield's main attraction lies in its quests. Both the main storyline and the faction quests are satisfying. The sense of curiosity they evoke is great, often leaving me eager to see more. Random quests you stumble upon in the open world can be equally entertaining.
Ship customization: Tweaking and personalizing my spacecraft was an enjoyable experience.
Places to Explore: The game has some locations begging to be explored, with beautiful landscapes on some planets.
Skill Tree & Dialogues: The game's skill tree offers an interesting challenge, requiring both leveling up and meeting specific challenges to unlock abilities. Dialogues and decision-making play a pivotal role but don't always lead to jaw-dropping consequences.

Looting and Inventory Management: The number of unnecessary lootable items in the world can make looting tiring. There is no sign if an item is valuable or garbage. The game's inventory system is also terrible, though some mods greatly improve this.
AI & Combat: While the game has good combat mechanics and decent weapons, the AI often feels outdated, lacking the intelligence expected from a huge game like this.
Space vs. Land: Contrary to expectations, a significant portion of the game occurs on planetary surfaces. The space combats are engaging, yet fall short of perfection.
NPC Expressions: The facial animations and expressions of NPCs are awful.
Empty Places: Certain areas, like New Atlantis, felt lifeless.
Optimization: Game could benefit from better optimization on PC.
