I don't know if "correct" and "fun" are at odds with each other. There are very famous examples of games failing at the start because of bugs like Cyberpunk. There is a point where the game is too broken to enjoy. You want games where the correct behavior is the fun behavior. (However, there are counter examples like Goat Simulator.)

To be fair, I don't pretend to know how CDProject developed their games. They might already have testing and the timetable was the problem.
