The people who review board games are ... a special bunch. Those games are very popular and well ranked, but they're not considered "best of the best" by people who "seriously play games".
One of the best usages of BGG is to find a game you like, and use it to find games that are like that one, and see what you want.
I know how it is. Some board games are almost like strategy video games with the amount of detail and immersion. Usually those same board game groups play D&D or something as well, like my housemates back in college. I just never liked those. If I'm gonna play a serious game, it's something simple with depth in play style, like Diplomacy.
