Uhh, I just came here looking for other survival games. But since you have minecraft (like me) I do have another game to suggest.
Haven and Hearth.
Description: You are plopped down into a random forest area and you need to fight to survive. Fight as in chop trees make wood build a house. Its not a 3D game but its more 2D. It does have a crafting thing but its not as good as minecraft. Its a online survival game. BUT you need to get protection because Bears boars and other things that can harm you. Once you make a good town and stuff and get far in the game, You can buy a skill named: Rage. It makes it so you can attack other players. So once you make a town you can practically fight other town. (Please note there are things like griefers. They enter your home and steal stuff and leave stuff bad.) Luckly Their are claims which make it so they cant enter. One downer about the game is Once all your HP hits ZERO, Your character gets deleted. Although i suggest you and a friend start together. If you want to make a town with me. My MSN is [email protected]
Well, I know this is a late post. But yea good luck!
