First reported in a story on OnGamers, if you're signed up to take place in League of Legends' League Championship Series, your contract bans you from streaming any game that can even remotely be seen as competition for Riot's online juggernaut.
That doesn't just apply to streaming other games alongside their LoL broadcasts. It bars them from streaming other games for the entire duration of their LCS contract, regardless of the time or duration.
It's a funny list; while there are obvious inclusions like LoL rival DOTA 2, there are less obvious inclusions like Demogod and Fat Princess, games I had no idea people even played anymore, let alone streamed for others' enjoyment.
Perhaps more controversially, the contract doesn't just stop at games competing with LoL. It covers entire companies. So LCS gamers aren't just barred from streaming StarCraft II games, they can't cover any WarCraft or Diablo content either.
A Riot rep later confirmed the move on Reddit, and his comments... make a lot of sense, at least as far as where Riot are coming from with their moves to legitimise LoL competition.
We say this all the time: we want League of Legends to be a legitimate sport. There are some cool things that come from that (salaried professional athletes, legitimate revenue streams, visas, Staples Center), but there's also a lot of structural work that needs to be done to ensure a true professional setting. We recognise there may be some differences of opinion in the perception of pro players' streams. In the past, pro gamers only had to worry about their personal brands when streaming and, at most, may have had to worry about not using the wrong brand of keyboard to keep their sponsor happy. Now, however, these guys are professionals contracted to a professional sports league. When they're streaming to 50,000 fans, they're also representing the sport itself. I can't stress enough how these guys in the LCS are on the road to being real, legitimate athletes. This is new territory for a lot of teams (especially in esports), because the transition goes from being a group of talented individuals to being real icons of a sport and a league. Similarly, you probably wouldn't see an NFL player promoting Arena Football or a Nike-sponsored player wearing Reebok on camera. Pro players are free to play whatever games they want — we're simply asking them to keep in mind that, on-stream, they're the face of competitive League of Legends.
