Like do i need servers and stuff what tools/ equipments do i need to put a game like that online?
You need a server, a bunch of programmers, artists and musicians to actually build the game. Oh and probably a couple of hundred thousand dollars investment capital 
A dedicated server is almost guaranteed to be required if you want the game to have a decent number of players (read: 5+) on at once.
As far as money…Unless you know a lot of people who will do a LOT of work for free, you can expect to be paying people’s salaries. Your programmers, artists, musicians… they all need to eat. 
What kind of server? A big one.
But seriously, creating a game like that takes a lot of time, work and patience. If you’re not sure what kind of server you need, I’d suggest not starting this project until you find a friend/ associate who can help you with the technical aspects of creating, hosting and managing such a game.
Yea I know it’ll take a lot of time and stuff, but what kind of server is needed to host a game like that a dedicated?
when you say hundred thousands of dollars investment capital what do you mean?
What kind of server? and what you mean by hundred thousand dollars investment capital?
