I put diff on master since I was expecting the game to be a quite a bit easier than previous TES games, I'd say I wasn't mistaken.
Quite frankly as a lvl 27~ mage I haven't had a real challenge in about... 15-20 levels and I don't even have to abuse the rather terrible pathfinding AI and AI in general. Levels around 5-10 or so where a bit of a bitch since I had no apprentice destruction spells, so I had to be pretty resourceful with using traps and a sword I enchanted with some minor fire enchantment.
Once you get the perk that allows destruction dual casts to stagger enemies nearly nothing is challenging in 1v1s and mass fights can be solved by just having a decent summon on hand since everything from weakest zombies to frost atronaches can tank the enemy for a time more than enough for me to regen the mana for their summon + some other spells. Once you get shouts as a mage it's essentially a steam roll, I just finished the Stormcloak rebellion vs Empire quest line without even having to reload more than once or twice where I died out of stupidity more than anything else.
The only enemies that really are bitches are the liches (dem rhymes) since they can take over my summons and they cast the lightning "nearly-hitscan" spells which will take a big part of your HP.
Dragons are more annoying than epic, since with the spells they can just be kept midair stunlocked without even breathing on me.
In short I'd say the gameplay has improved, but it still feels more like a game than a "world" like morrowind was. Also the UI is sometimes unresponsive and clunky shit in general, I never had a problem with the one in morrowind or oblivion.
Some of the new books are a nice touch, though I can't help but ignore that nearly all are just recycled from previous games.
Oh and I play an imperial mage, which doesn't seem like the best option. Bretons keep being OP imo throughout TES.
Overall enjoyable game that imo didn't live up to the hype, similarly to the last installment before it.
