I first learned about Shadowrun through a magazine, probably Xbox Magazine or Game Informer, and I immediately fell in love with the concept. As a young teen, it was my first introduction to anything cyberpunk, and it was so cool and unique. Once I got the game, it was also special, because as someone that didn't have a gaming PC, it was my first introduction to Counter-Strike style gameplay.
When Rooster Teeth, which I had also recently gotten into at the time thanks to Red Vs Blue, made a short series using the game (1-800-MAGIC) it just cemented in my mind that this game was something special.
The community in this game is still alive and well, playing on peer-hosted servers using old Games for Windows Live codes, communicating and setting up tournaments and such through a dedicated Discord space. They were even able to put together a Q&A with some members of the dev team a while back. With over 1000 members in the Discord, this community is more active than many games still being officially sold and run. I can only imagine how much it would grow if there were easier access to it via GOG.
