+ Just gotta ask yourself if you do this because it's still fun, or if you want the biggest audience regardless of the game. There's nothing wrong with either option. I could make MOBA videos and grow my channel more effectively, but I don't because I still like playing Starcraft.
Thanks for reminding me Jay. I make custom content before in many games, such as Spellforce, Dragon Age, Skyrim even the sims because I love it. SC2mapster is a great place to share everyone's CC. As long as the download counter on everyone's project page still up and running already shows that people still love playing Starcraft. They may not make comment or give feedback but they've been here.
That (IMO) is already a tremendous achievement on its own.
