As someone who bought the game Day 1 I can understand everyone's fury who payed for MKX and HSV shouldn't have released a port this problematic, but...
I'm a big fan of the MK series and when I see what has happened to the PS3 and 360 owners, I consider myself lucky. I could play from the start, first it was only 30-45 minutes then memory leak crashed my game. Then came along the patches and while I had issues and online was unplayable, I still could learn my favorites, I unlocked the whole Krypt, finished the Story and I beat Klassic Tower with all kombatants. And I had fun. I had more fun than bad moments.
So, honestly: do you still think that a delay would have been better? MKX as a port is not a great experience but as a game it is. And I find it has been better to be able to play from Day 1 with all the issues than waiting for months and watching the streams to see how exciting the game is - only on new gen consoles.
