Comment It worked for me, running a game server (Score 2) 45
I ran five Battlefield 3 servers on two continents for a group of about 3500 registered users, and before that a Bad Company 2 server in America for a year or two. We had a Steam chat bot (IRC is Dead in this era, especially for games) that you could interact with and kick unregistered players. The first version was crude PHP run off of a godaddy account to register your account for Bad Company 2. The steam chat bot was some ruby glue code triggered by an AutoIt script/executable.
But later with Battlefield 3, we rewrote the whole system from the ground up. ChewieBot was a C# program that used an OpenSteam API dll, and called a URL via json which authenticated against another guy's custom Steam Authentication db (he handled the backend registration using the offical Steam API) and then we ran a python script from there to actually connect to the server and kick the guy(s). This actually ended up being so successful that we were blacklisted by the reddit guys on multiple occasions despite being a top 10 server. Another guy did the website redesign including custom CSS work. I didn't do very much of the coding, most of my skills were in project management and having the technical knowledge to pull together resources and people and make them work.
Over four years I worked with about 20 people in total to make the system happen and keep it running, plus bringing in regular funding to pay for the servers, mumble servers, and the actual game servers (never pay for your own servers, you're already giving them your time). All in all the project spent about $3500 in hosting, mumble server fees and the lion's share, top notch game servers (about $114/mo each) over four years.
I ended up getting the job with those project management skills I learned while putting everything together. I write a lot of server scripting/automation and also project management working with business analysts and our appdev team(s) for various internal groups' dashboards, interfaces and whatnot.
At least one other guy used the ChewieBot project to get a job as well, he added the json capability to give him a talking point in interviews. The guy who did our db back end already has a job doing C# stuff at an advertising data mining company in the UK but is pretty fantastic at what he does. With all the API hooks, free or nearly-free VPS hosting and a popular game it'snot difficult to build a reputation and portfolio (not to mention the real-world skills of dealing with true nerds) that will take you places.
