Boring is not the same as Bad
an example of a Bad Game is The last Guardian, everything about that game was TRASH, the controls, the combat( if there was any) and story, the graphics, the characters, the pacing, the environment...Etc, i can't think of anything good in that garbage game except for Trico's behavior, the game is just broken and it's a disgrace coming from the same people who made one of the greatest games of all time, Shadow of the colossus
and example of boring game, Nioh, it's a good game but it's VERY repetitive, you fight nearly the same enemies through out the whole game in almost the same environment, that was a boring game
i prefer boring over bad, if the game is bad, i can't play it at all, if the game is boring, i'd take a break every hour so i don't get bored and keep playing
