Know a creative strategy game multiplayer?

Something like warzone 2100 or Minecraft

Something with creative abilities to like make units or like add your own sprites to and play with other people…

And when I say strategy I mean like buildings resources and money…

Please let it be a free link rather than a demo

How about Goodgame Empire?

hope this would be helpful.

If you want shooting then battlefield is for you
If not you can play the 7 days to die its like minecraft but with better quality and has zombies and you can build and do the stuff you mentioned above hope this helps
