The client crashed in every single one of the games I tried to play today

In all 4 of the matches I've tried to play, I've waited out 20 min leaver buster penalty times (thank you client crashing), only to get into the post-champ select loading screen and have the client crash, which I guess resets the leaverbuster penalty.

Now, I'm back to the bottom of S4 after having grinded to a career high of 60 lp, which may not seem like a lot to everyone in gold+, but it was a pretty sweet place to be from my perspective.

I'm honestly at the point where I don't even care about the game anymore. Either Riot employees don't care enough to fix the client, or they just aren't smart enough to - quite frankly I'm leaning toward the latter. All this in mind, I have only one question:

What's another PC (preferably free) game I can get into?
