One of the most expressive and satisfying level curves in any game. Extremely good worldbuilding, main quest, and themes. My current favorite game of all time.

Three primary flaws:
1. The game is bad at explaining itself. How stats and skills work, how enchantment works, and so on are poorly elaborated on. I have 100+ hours and still get blindsided by the particulars of magic at times.
2. Jank. It's an old game. OpenMW helps, but there's some things you just can't fix.
3. The expansion content leaves a lot to be desired. Given that both expansions are meant to be played after the main game, the enemies' damage is cranked so far through the roof that you can be swinging an ancient blade of the gods, forged in the heavens by the immortal deity of war and enchanted with the most powerful magicks in the realm, and do maybe 1/5 of a sewer goblin's healthbar. Then the goblin one shots you. And unlike the base game, these expansions are heavy on combat. You will be in those sewers a lot. The stories of the expansions are good and continue on with the main game's themes well, but console commands get extremely tempting.
