The top 100 is like a popularity contest among girls in high school.
Some are there because they are pretty. Some are there because they are smart. some of them are because they are easy and fun.
The reviews are a wealth of information. Use those as it gives you a better understanding of the strengths and weaknesses.
I love ID4, it is a fun game with a great theme (albeit shallow), and Jeff Goldblum and Will Smith are in it... FUN. It ranks like 200 something... not realistic in my eyes. But that doesn't mean I don't like it.
Many times, it is not the pretty girls that give the most pleasure
