Okay, you expected a big patch, me too (!), and it all ended as a enhanced edition WITH some new requirements on top of that ! I can understand your frustrations when I try to imagine your situation (but honestly: I never can that for 100 %).
The Unpatched game (in his current state) is still a very good & magnificent game to play ...!
For me that's fine, but as I can clearly understand, not for you ...
I've still full confidence in the Larian Team, don't understand me wrong, but one thing you, Larian Studios, must try to understand : as always I'm afraid, you're all mostly (TOO?) Ambitious/Enthousiastic ! Therefore they take, as almost always, too many hay on their fork starting a big update ...
So that's like a knife that cuts on both ways !! And now it depends on which side you look at on the current matter : all the negative or all the positive ... (or in between) !
But, like always, at the end, I strongly appreciate their enthousiastic developers work !! That's the largest reason why I love the Larian games : all the hard work they did in each of their games gives that good feeling : a game maked with Passion & Love !
On 7th of february 2015 : I start a new adventure in the Divinity world of Original Sin, it's a Fantastic Freaking Fabulous Funny ... it's my All Time Favorite One !
