I just got Life Is Strange: Before The Storm and I IMMEDIATELY fell in love. So much I just bought #2 today, because I couldn't find the very first one. 2 doesn't have to do with the other games though, so I'm going to play that while I'm waiting for the other one.
I think the game order is
Life is Strange: Before The Storm
Life is Strange
Life is Strange 2
Life is Strange (2021) The new one that's coming out
