Depends in what gameserver are you trying to host, also it really depends in how much time and money you're going to invest in the server, also using a unique/enjoyable gamemode and inviting your friends to create a small playerbase will help you in growing the playerbase. On a side note, even if your gamemode is enjoyable, no one will know about your server till you properly advertise it in community forums, and as well you should invite your friends, and advertise it in social media groups that's dedicated for the game you're hosting, steam groups also.
