yeah i did read it, except i don't do commentary and would just like clarification on cutscenes, dialogue, and mainly the tower's soundtrack, because i don't know if strikes due to snippets of audio and cutscenes were from you awesome guys at Bungie. Thank you for replying, i really do appreciate it, as i thought no one would reply.
If you're actually playing the game, then you're probably fine, as your gameplay is -your- gameplay.
If all you were doing was standing in the tower or just running/jumping around with no real actual gameplay and just listening to the OST in the video, that would most likely not follow the guidelines.
Unfortunately, as I'm not privy to Bungie's methods of choosing what is and isn't okay outside of the guidelines above, I cannot say for sure whether what you're proposing is fine or not, and Bungie is likely to not respond since their policy is there for everyone to see.
With that being said, again, if you're actually playing the game and putting effort into your content, I, personally, as a player and random person on the internet, would think you'd be okay.
If you have doubts on whether or not the content you're producing follows the guidelines, the best bet would be to add more of your own spin/creation/activity to it to ensure you're following the guidelines. While Bungie estimates about 20% of your own content is fine, if you go 30% or 50%, then you're definitely fine.
Please also note that if you're playing the game muted or extremely quiet and just have the OST as the only audio, that may also get flagged, as it's not really any different than a video with a static image just playing the song. I'd recommend not doing that. If you're going to play the game, it's best to play the game as intended and not try to toe the line to sneak the OST into your video.
Ultimately, it's up to Bungie whether or not your content is acceptable, so, your best bet is to make sure your content is acceptable from their point of view. If it's iffy, you should rethink what you're going to do.
All right, that's awesome! Thank you so much for your guidance and assistance. Again, i really appreciate your replies, as I thought no one would reply.
