People say this to sound smart always like its something super technical and difficult and us plebs would not understand. The reality is that the actual good feedback that does change the game and does actually find balance issues, exploits and bugs, and design issues, as always with PDX games releases, is the one players give once the game releases and everyone can actually test it.
Yes, QA might be good at catching bugs that would otherwise cause crashes so that is what counts to them as a "polished release". But the issues which mud PDX releases are usually the ones brought up by the actual players which "magically", nobody found before despite running "betas" and having QA and what not.
So having 5 guys giving supper well thought out technical reports is very useful. It will never be as useful as 5,000 people finding all the bugs, balance, and design issues that no professional team could ever just because of lack of capacity and scale.
I just hope this time is right and we dont get yet another release mudded with issues because, once again they refused to give access. I really hope that the only issues with the game are the ones being reported by the youtubers and the community, for the first time in a PDX release and it is super smooth and there cannot be negative feedback after release. But I doubt it.
And im not saying the game won't be good. I know I will love it no matter the balance issues or bugs it has. I just know they will get a shitstorm because of it because other people dont see past that and are looking for any excuse to crap on PDX and review bomb their products and be proven right on their crusade against "Paradox shitty practices". I know releasing games as a beta/alpha does not look "professional" or "flashy" or like a "respectable triple AAA company". But it is a safe bet.
I just reaaaally hope I am wrong and with just the few people they have they find all the balance issues and bugs by release and its super smooth. But after seeing the state the the game was given to youtubers with GLARING issues that anyone playing 10 hours would have picked up, forgive me if i lose a bit of confidence in their strategy of "only a super small tight circle of people will test the game".
