I would say the problem is with 2020, not 2077. Everyone is a critic these days and just like people claiming to have extensive medical knowledge; they have extensive knowledge into what it takes to create a AAA video game. Nobody is happy anymore.
The game is great. Runs great. Story is great. Characters are Great.
The gameplay isn't the best, I will say that. It defiantly is not unique. Its like borderlands and Deus Ex had a baby. Which neither of those games had amazing gameplay as is.
The bugs I personally have experienced are very minimal. Update your graphics drivers. I'm not defending the optimizations or bugs on any other system other then PC.
