CDPR deserves all the backlash, and i say that as a bit of a fanboy. No matter how much i like the story, world, side quest, you just can't turn a blind eye to what a horrible launch this has been.
This is a 60$ game, and it was broken for so many people, mainly console players, but let's not pretend that the pc version is perfect either.
I feel sorry for the people who have been working a long time on this, to see all your hard work getting smacked around like this must feel bad. They clearly have very talented people at CDPR, but some of the higher ups decided that the game should be rushed out for whatever reason and it's now coming back to haunt them.
I don't believe a company, even without external testers, can look at this game before launch and say "well, this is ready for launch". Where they go from here i don't know. Hopefully the game can still be worked on and fixed with patches.
Multiplayer could be a potential cash-cow for them, and the world has so much potential, but it needs a lot of additions and fixes for it to be relevant.
