"Everyone bought it and there are no more customers!" because TF2 still makes money and way more people have it than us.
What I meant was more like "Tons of people that bought keys long ago are still playing and hardly any people stop playing blockland! Gee, there are so many active players now and more coming every day! "
So, what I was thinking was if there will ever be a point in which supporting the increasing number of blockland players as well as old players will ever become more expensive than profit from newcomers.
