I used to love Spiral Knights, but the Devs keep changing it for worse with every update they release, sadly. With SK no longer being the game I once loved, I think my favourite F2P game nowadays would be Path of Exile.
PoE has its many flaws, but at least it's truly FREE.

On Steam: DC Universe

And in general: Smite

Ghost Recon Phantoms and Fistful of Frags

Currently Hearthstone & Warframe, in the future will probably be Heroes of the Storm.

World of Tanks, World of Warcraft (I played the Official server and I feel like it's free because everything you get there is with your effort and not paying for them hu3 and the excelent costumer service)
