For the record:
The Witcher 3's development budget was $32 Million and that game looks fantastic:
"The Witcher 3 took around a 120 million PLN ($32 million) to create. On top of that, CD Projekt also had a $35 million marketing budget for The Witcher 3, putting the total amount of money spent of the game at around $67 million."
I think they should have aimed higher, did better stretch goals as well and tiers. Honestly could have gotten much more if their stretch goals weren't so meh.
