The bigger a game, the more bugs there are. Also devs dont always want to fix bugs, because it gives an edge to players who spend more time on the game. For example in bdo you can infinitely stack weight on your horse, which is treated like a normal game mechanic at this point, or you can powerlevel certain skills with a bug concerning rare drops
I didn’t understand the bdo thing but yeah I guess fixing a major bug takes a lot of time
no it doesnt tbh, if it's not gamebreaking, it can become a feature instead of a bug, like my 2 examples about black desert online
consider how paradiso was more than 10 years old, it sure has a lot of major bugs
