RPG Codex is one of the best internet sources about quality RPG gaming, they will give an honest and at times brutal judgements on every new RPG. They are every developer's worst nightmare, or if they created a good game it can be one of the most uplifting experiences for the devs if they were praised by the RPG Codex community.
When a site like that creates a top 50 list of the best Role Play Games ever you need to trust the list and quickly try to find any one of those games if you missed them.
As a harcore RPG player I played most of the games from the list and I definitely recommend to try any of those games, perhaps skip only those that are released before 1995, those do not age well.
Also another note Witcher 3 is not included because this list was created few years ago, but today it is as legit as ever.
Do you agree with this list and how many games from top 10 you never played?
