What are the best free games on steam?

Emily is Away. It will open up your old wounds!

The Abbey of Crime Extensum

http://store.steampowered.com/app/474030/

Based on an old game, based in the book and movie "The Name of the Rose"

Cry of fear

Since apparently you like VNs:

Narcissu http://store.steampowered.com/app/264380/ A classic, pretty depressing though

The Sad Story of Emmeline Burns http://store.steampowered.com/app/429940/ Anything by ebi-hime is great, but it's her only free VN on Steam for now (there are more on her itch.io page)

Voices from the Sea http://store.steampowered.com/app/348620/ Probably more for teenagers, nice to play in summer

Also seconding Eternal Senia, Princess Remedy, Emily is Away, Expendabros and You Have to Win the Game.

Depends on what you are looking for but, probably:

Team Fortress 2, Dota 2 and Path of Exile.

Also Smite and Paladins.

Warframe looks cool too.

Oh! And I forgot about brawlhala and evolve (but I think this one is dead again)

Realm of the Mad God xD

Path of Exile is for me the best free game i have played,the community is huge and they constantly support and put new content and expansions in it.I also liked it more than Diablo 3.
It's fun if you play with a party but loot wise is better alone because you pick up everything for youlself.
Be careful you better check up some builds before starting because you will end up with a crappy passive tree and doing no damage at high level maps.
The only minus is that you probably need to buy stash pages because you only have 4.i haven't bought any in my 254h in steam+many more in PoE client and i managed to play well with only 4 pages but it's way easier if you have extra stash.

evolve stage 2

Khimera is a pretty neat platformer

If you like classic point and click adventure games, you should try out Heroine Quest

http://store.steampowered.com/app/283880/

It's an homage to Sierra's Quest for Glory series. It's so long, polished and satisfying, they could've easily charged for it. But you can get it for free.

Clicker Heroes

unturned....

Planetside 2 if you like giant multiplayer FPS games (really giant). Tho I havent played it for quite some time already so I dont know how' are things with the player population

Marvel Heroes 2016 is hands down one of the best free 2 play games on steam. If you like ARPGs like Diablo, Path of Exile, Torchlight and are a fan of superheroes and Marvel.

Brawlhalla is a game like Super Smash Brothers.

Magic Duels is a great CCG

Duelyst, Faeria, and Chronicles: Runescape Legends are awesome hybrids of card and board games.

Tree Of Savior is a good MMORPG.

Paladins is a free 2 play version of Overwatch.

Starbound is a good Roguelike Platformer MMO.

Emily is Away

Khimera: Destroy All Monster Girls

Spellweaver, if you wanna give a card game a shot.

I like free games.

• TERA - MMOARPG. I love it.
• Eternal Senia - ARPG made in RPGMaker.
• Unturned - A simpler, smaller voxel version of DayZ. Still better than DayZ.
• AdVenture Capitalist - Cookie Clicker, the money edition.
• World of Guns: Gun Disassembly - Taught me how a gun fires. 10/10.
• Dirty Bomb - Overwatch before Overwatch was cool.
• Floating Point - Fun for a few hours. Relaxing minimalist game.
• Spooky's Jump Scare Mansion - You'll spend days recovering from the shock of fear this game will cause, and all of this time you'll be asking yourself over and over again, "HOW THE FUCK IS THIS GAME SO FUCKING SCARY WHEN IT'S NOT EVEN SCARY?" Crazy fun. Good for parties/streaming/Youtubing.

Warframe
Team Fortress 2
Card Hunter
Mandagon
Duelyst
Evolve Stage 2
is what I played and liked so far

Dead FP2 games that you should have played are Nosgoth, Battlefield Heroes, District 187, Battlefield Play 4 Free, Battleforge, Need For Speed World, Arctic Combat.

Armorgames.com has a load of great free flash games I can name.

I love F2P games, their meant for people like me who can never buy games on our own.

It took me more than a hour to write all this for you on this tablet, why didn't you just press free to play games and press popular...? Why do you have to ask for things handed to you on a plate...? Don't make me regret spending my time on you please.....

Mabinogi

Oh i didn't know Price.
It looks nice.

Well if you like fishing, there is Fishing Planet.
Ok i haven't gone far enough to know if you need to buy some packs at some time to go further :)

Path of Exile

Eternal senia was my favorite same last year so I go with it
