Steam games that require login and a legal view question

[GazCBG]

Hi,

 

I noticed on some Steam games, that Steam requires you to own it, to be able to install the server files.

 

Now from a legal point of view, if I was to own said game and sell servers, would I require multiple licenses for said game, or can I run multiple servers from my one license, for other people?

I made the experience with arma that i was able to host multiple sessions with the same account. Don't know it that changed by now or if other games have different rulesets

Depends what game it is. Some games are simply impossible to run multiple servers under the same account while others allow you to run as many as you want.
