Unity questions,i plan to start my project.

I plan to start work on my new project titled TheLife ,an online sim where you do anything with other player,stand and chat,“tag them”,so you both go around and not lose each other,be on the in game news,rob a bank,etc,get hungry ,buy food,stamina etc,but is it possible with unity?,i want it as cartoon style,can unity do it?,can unity make a large network of servers etc?,if so ,i would like to know how i can go about the project.

Thanks.

*My unity has a problem,i add the 3rd person prefab,hit play,and he sinks forever.

Take a step back you’re talking about a high level game project.

Unity can do just about anything, but if you have a problem like your game has no collision and you dont know whats wrong you might want to learn to walk before you start running. Go look at the basic documentation, you’ll learn what you’re up against.
