Good online free PC games?

I'm looking for stuff similiar to: ROBLOX, Minecraft, and The Sims. I don't like RPGS.

I would suggest Garry's Mod but it's not free.

I would suggest Pirate king international and Rage of 3 kingdoms game. Play free Online on Gamernizer.

I'd suggest you try Goat Simulator 2014. Or at least MechWarrior for free at http://toomkygames.com/games/mechwarrior
