The release of the game really hinged around the system you had at the time of launch. I really wanted to buy the game prior to launch, but I'm glad I didn't. All the promises CDPR made sounded awfully familiar to all those promises Hello Games made about NMS.
I didn't purchase the game until I had a PS5, and the Playstation Store put it back in their queue (PS4 version). I bought it on sale, yet a week later it was going for like $25 IIRC. I should have waited, but whatever. And there were minor issues, but the game was not broken like the clips I saw at launch. And I'll say it again, despite all the promises the studio made, a lot of the problems revolved around the specific equipment you were running.
The dev kind of does have a point, there was some overreaction, and seriously how many times are gamers going to continue to trust studios to deliver on their promises to these kind of games? However I believe he's painting a different picture at a critical point in the game's history where its first expansion is on the horizon.
And you see these same promises coming from the studio. The tone sounds so similar. Don't buy the DLC until after launch...I'm not. Wait to see the game reviews before buying. The only way publishers will stop making these overblown promises is when gamers stop pre-ordering games and expansions, regardless what carrots they dangle.
