According to Vincke the studio is grateful for the feedback they received during the development of Divinity: Original Sin. So now the studio is hoping to get the same kind of feedback during the development of Divinity: Original Sin 2.
Larian’s is already investing enough money into Divinity: Original Sin 2 to do “cool things” as Vicke put it. They are hoping to add the funds from the Kickstarter on top of what has already been invested to make the game even better just like what they did with the original Divinity: Original Sin.
