So I'm gonna bring up something I did mention in another thread, but Roland shot down.
I still absolutely believe that releasing A17-E NOW is bad idea. We're in the middle of Fallout 76 release, some folks are still going hard on Red Dead Redemption 2, plus other games have also had updates (Overwatch just got a major patch to fix lots of stuff and prep for new stuff, Warframe just dropped it's expansion, etc).
The ones in parenthesis likely won't apply to this community, or people interested in this type of game, because I'm pretty sure I'm the only idiot here that plays Overwatch, Warframe AND 7DTD.
However, Fallout 76 is the big one. It just released yesterday and TFP want a stream event to build hype in the middle of that? Sorry, but that's a competing genre game... and way bigger. I hope I'm wrong... I really, really do... but I don't see how this is going to help from a marketing standpoint in any way just because of the TIMING.
What I personally would have done, based off the conversations I've had with Indie and small studio game dev friends (I'm a geek, I like learning about this stuff) is something like this.
Stream event on the 30th so it's technically released in Experimental in November.
A17-E for the public on the 3rd December.
Look at "stable" release around the 21st of December.
That allows the RDR2 and FO76 hype to die down (plus Overwatch and Warframe hype for anyone who cares about those). You release just before christmas with plenty of time to fix the REALLY bad bugs, which lets people play over the holiday period AND you hit the steam sale window.
If the stream event was about generating publicity for the game and building up hype, then my personal opinion is that would've been a lot better (I also want to state I made some assumptions regarding steam sale dates, so adjust accordingly).
