Anything above a 6/8 in rating is worth reading. Games around 5/8 can be really good to some people but general lack in some important aspects which generally makes them more niche or less engaging. You will find some genuine good ones at this rating though. A 4 generally just means it's boring, underdeveloped or lacking a lot, And anything below a 4 is usually very bad, if it's a 2 it gets to the point of it being so bad it might actually be funny, So worth a read.
