But yet if they released it Early Access to crowdsource their QA, people would have dogged all over them about "what's with the EA bullshit, just release the full game when it's finished"
Personally, I'm a huge fan of Early Access, I like playing 3/4 finished games and having actual tangible input on the finishing touches. It's made several games that I already really liked in their EA state, into masterpieces.
But your average gamer just wants to buy a game and have it work perfectly. When it doesn't, tantrums happen.
