winner.tf
I started this as an experiment. Because players were unhappy with the Team Fortress 2's built-in casual matchmaking system, I wanted to build a community of pure stock game servers with no gameplay-changing plugins installed, which is the opposite of what titan.tf is. The main focus was putting minimal clutter to the gameplay experience.
However, after running this experiment for a couple of years, I realised the demand just wasn't there. I was spending a lot of money on servers that were barely used. I decided to shut down the project and focus on other things.
We did manage to gain a community of 200 members who supported us during this time.
