I must admit, when the game first released, it was definitely rough. I did not understand the critical acclaim. If it launched in the state that the game is in now, the high acclaim would be justifiable. However, like you said, the game was incredibly unpolished and glitchy at launch.
Yeah, it was rough. Still, I think that the gameplay and open-world have a lot of issues. Gameplay is really clumsy. I get that it's not maybe the focus of the game, but the movements are not responsive enough. It was distracting at times. And I also think that the scenarios are far from stellar, except from the bit cities, which were really well made. Also, the main plot is really bad. But, well, I can tell that the focus of the game is not the main plot, it's the world itself. Except that the world is not well-made enough to make it worth my time XD. I still hope it sells well, because there are Bethesda franchises I enjoy and I want them to keep releasing games on the Switch. DOOM is an awesome game, at least.
