Yeah, i also completed the complete saga yesterday, but it took me way less then 100 hours, and i've done about everything there is to do (except spook the fortune teller and slay the infamous rabbit)
The story is very solid, something we see too little of in the game industry.
To be completely honest, the voice acting was a little mediocre at best, but you can't have everything.
Now, here's my biggest issue with the game:
The graphics engine.
I can run games like Dragon Age on max settings all the way without so much as a little hiccup or shudder. Divinity however, makes my PC feel like an old Intel 333mhz on medium settings. (and frankly, Dragon Age is the heavier game here)
That is putting me off of another playthrough tbh. Choppy gameplay ftl. I only managed to get through the one thanks to the story.
All in all a good product, but please, fix the engine.
