I have over five hundred games, some I haven't even gotten the chance to play yet. I will go through the process of ranking hundreds of games through diffrent generes and reviewing them while keeping a comprehensive list of said games and their ranking as opposed to eachother. The only creteria to be ranked is to be a game on steam and in my library. How the games rank is going to come down to a two factors, personal enjoyability and playability, and yes it's probably going to seem absoulty abatratuiry as I own over 500 games.
This process will probably be more defined in the future as I rank and rate more and more games.
