Thanks. It's more or less what I figured, but I always like to check. 

If nothing else, in the past, I've run across game content creators who license their work under permissive licenses like CC-NA, but ask that people not stream/YT.  So even if it's legal, out of respect for the creator, I prefer to make sure they are ok with it. 

I suspect in this case, if there was a reason against streaming/YT of UQM, this post would have been mobbed by people saying "don't do it"

Hey folks.  I'm a long time fan of StarCon2/UQM, and recently became a Twitch streamer and YTer (with very few viewers on either platform ).  I'm thinking about playing UQM on stream (and then publishing the videos to YT), and wondering if this is permitted by the UQM creators/copyright owners and if there are any known issues with doing this. 

If it matters, I'm not monetized on either Twitch or YT at this time, though that might change in the future.
