Best Free To Play Game

Fortnite, Planetside 2, Roblox, Paladins, Team Fortress 2 and Defiance

Warframe, Planetside 2, SWTOR and some of Wargaming's games (World of Tanks, warships etc) are alright, even with a couple microtransactions here and there.

Runescape is a great f2p game. You can even get the paid version free with in game money

Dungeon Fighter Online! An MMO with a ton of classes and subclasses. Flashy animations inline with popular action anime

Warframe, H1Z1 and Team Fortress 2,, these games are nice

Best free to play steam games: Path of Exile, Aion, Clicker Heroes, Tera, Black Squad, Cuisine Royale <- XD

I'd def go for fortnite, it plays like a premium game even though it's free, I can't get over how good the game is for something they don't charge for.

Runescape, although after you complete a lot of the "free content", you'll probably want to move on to a subscription, which really is worth it in my opinion.

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.

My favourite Free To Play games are Fortnite, Paladins and Soulworker. Paladins because it's a FPS, Fortnite the same and Soulworker it's a Hack and slash game with anime characters.
