But those aren't all the same. Yes, the games in the same category are alike because they are in the same category, but in your previous post you said that if you like one, you like them all, because they are the same.
Your basically saying if you like Mario Party your going to like Super Mario Bros. They are two different genres. While a person may like Super Mario Bros. for the platforming, that doesn't mean they will like Mario Party because it mainly is mini-games, it's a different style of gameplay. Same with Mario Kart and Super Mario RPG.
