Believe it or not, I signed up just to shout this out.
1- It's a mix of turn-based and real time combat. Sounds cool doesn't it? But all you do is keep pressing pause and try to play the game manually turn-based. Combat should be turn based by default, or at least we should be able to choose between turn-based and realtime in the settings (like Arcanum).
2- You need to pause every 30 seconds in order to understand what's going on in Combat, whether the tactic you apply works or not, which character's skill is more effective, etc. Because animations are at the level of mobile games even in Ultra graphic settings.
3- Lore, story and dialogues are cheesy, boring and uninteresting. From the very first minute, Calisca's cliché of "I am a character who has seen a lot, so I am cold-blooded" made me cringe already. Almost all the dialogues and side-quests are filled with these clichés. It's 2015 (the year the game came out) and we're still dealing with 90's hollywood action clichés.
Oh boy oh boy, I'm going to get lynched on my first post just for saying this, but Obdisian doesn't know how to write quality lore, captivating story and interesting dialogues (including New Vegas).
4- No matter what type of character you created, you always have to pay attention to combat-based stats, because you can't finish the game just by talking or hiding like oldschool RPGs. It's been almost 20 years and there hasn't been an RPG that you can finish it through talking like Fallout or Arcanum (Even in Dos 2 this is mostly not possible.). Why is that? Combat effects sells in trailers and E3 commercials, that's why.
5- Here's another "unpopular" opinion of mine: party-based RPGs sucks. Characters of different sizes and races following each other like a shadow looks very ridiculous from an isometric perspective, especially in towns. It kills the RPG soul and often ignores the character you spent hours creating when starting the game, because after a few hours you have to deal with companions more than your own character. The "official" characters created by the game overshadow the custom character you created.
That's all I have to say, but from those who loved the game, I would like to hear what is unique about this game.
