I don’t think its a No Man’s Sky situation. Cyberpunk 2077 suffered the most from high expectations and lies told while advertising the game. The game is decent, I personally enjoyed it a lot when I bought it for 20€ a year after release. But they did not go back and add things they promised but didn’t deliver on.
I am excited for the DLC and hope that it will be good. Its best to not buy promises tho. If the things CD Project Red promised are what is needed to make someone want to buy the game, they should wait until these things materialize.
