140$ seems too high for a game that I will have to wait for 2 years and trust it will be good.
I would suggest folks who are using the KS to "Preorder" or purchase the game to just wait 2 years and buy it when it comes out.
Just pretend there are no rewards and toss them as much as you want to support them and then be surprised when you get stuff later.
I don't preorder games... and tossing out money is a recipe to disaster and contributes to the decline of crowdfunding.
I understand where your coming from. However, Larian is releasing a free upgrade to EE and has released quite a few very successful games. The company has been in business since like 1999 starting on Divine Divinity (a.k.a. Sword of Lies) and going very strong. They are not like most developers trying to sponge as much money from their customers with BS DLCs as they can.
As for waiting 2 years, I'm expecting the alpha or beta to be released in about a year from now. Since majority of the mechanics are completed, I'm doubting any major delays.
