Best Free To Play Game

Path of Exile
Good looking game, addicting grind until it gets repetitive. But, still worth it, since the game itself doesn't look like it's free at all.

Cuisine Royale
Saw my friends playing it, seemed really fun, and funny.

Fortnite
I think it's a decent and full game for the price of nothing, and has a huge player base which is a good thing. People who hate this game are just sad PUBGers.

Realm Royale
More and more battle royale... this one with a twist of RPG. I played a couple matches, it's fun but needs balancing and bug fixing.

TF2... I feel like the community might be dying.

I remember Evolve used to be a payed game which turned free. Reason is, it's not worth a full price game... or wasn't. Not sure about it's status now, I just know that some people get a kick out of it.
