It's funny how gamers keep complaining about how the devs don't play their own games... one of the very few streamers I actually will watch is actually the creative director for ESO(Rich Lambert aka Slashlurk) who happens to stream... ESO. Though honestly I'm not usually watching to see him play - he'll answer questions about ESO(provided it's not related to upcoming content) and sometimes tell stories about it's development, so it's neat to get those insights or inside peeks.
Like the time a relatively new security guard at Bethesda encountered Todd in a hallway and asked for his ID(and turned a peculiar shade of white when he saw whose ID he'd asked for). He actually still works there to this day and considers it a badge of honor.
Or like how the Stormhaven zone was redone 9 times before release because that was their prototype zone and they were still figuring out how they wanted to tell stories in ESO.
Or how Rich got initially put on ESO because he was the one constantly harassing Todd to make an MMO of Elder Scrolls in the first place. And One Tamriel, which saved the game, was half him(and half Matt Firor). They spent Christmas weekend brainstorming it out before they took it to the team. And even then half the team thought it was a crazy idea at first.
ESO's voice-acting everything was something he was initially against, until he actually saw it in action, and was impressed at how much it did affect immersion - and then he was all for it.
(One of the few time I go to explicitly watch them play is when they get a few regular ESO streamers and devs together for their "Tipsy Trial" nights on Thursdays, and that's mostly to see what shenanigans they're going to pull, since they usually do something stupid that makes it harder on themselves.)
