Your favourite free-to-play game?

dota 2, tf2, smite :D & formerly i play PoE but recently i'm bored with it

Doto :)

Fistful of Frags, Path of Exile, You Have to Win the Game, and of course, TF2.

Loadout

Smite

World of Tanks, Path of Exile and Warframe. It varies over time :D

I've yet to find a 'good' free-to-play title. I guess Old Republic comes closes, even though I paid subscription.

DCS: World

Aerena - Clash of Champions, really like the game and the awesome devs

GunZ The Duel (NOT GunZ 2), because it's not only fighting like everybody thinking its much more and you can do something that called "Superdash" that is fun too.

Vindictus. Graphics and gameplay were nice.

And Path of Exile is great too! Best Diablo clone I've seen... Nuff said.

No More Room In Hell is alright

Path of exile, league of legends(but the "buy champions every month" is a cancer, i think that i should move to dota2), warframe, hearthstone.

Dead Island - Epidemic and Magicka - Wizard Wars

Star Trek Online

Not sure if flash games count but Box Head is awesome!

doto tvo

Dwarf Fortress. It's just epic, mindblowing, and deep ( joke inside ).

Mechwarrior Online is fun if you like the old ones, hawken is fun for a quick game but the tempo is too quick for my taste, star conflict runs on linux, urban terror is a lot of fun and runs on linux as well.

Haven't really played many - I'll go with Trackmania Nations Forever.

Marvel Heroes, Smite and Warframe

I really enjoy(ed) playing Spiral Knights, Path of Exile and recently also Heroine's Quest: The Herald of Ragnarok.

My favourite F2P browser based games are Shakes & Fidget, Zombie Pandemic and Die2Nite (you should definitelly give them a try when you're bored some day!) ;)

I love alot of F2P games so its a tough choice but i will go with Infinity Wars, im seriously hooked into it. Besides it i love soon to be F2P Defiance. Lodeout, Heroes of Newerth, i used to love Battlefield Heroes and Crimecraft and i would realy love to try Gunz 2 the duel and ArcheBlade.
