Before DAO was launched, I spent months watching gameplay videos, reading every preview and info there was about it. I think I even used some vacation days for it's release. Ofc I got the deluxe version with all avaiable dlc (at launch)
And I had lots of fun. But it didn't last long. I played until the part where you finally have recruided all allies. Then I was kind of bored and left the game. Some time later I wanted to play again, but din't feel like continuing that game and started a new one. Let's say that the long dialogs are fun the first time, but the second time they are tedious. I did get elss further in the game this time.
Since then I tried to retake the game a few times, but I never managed to have fun again. I didn't purchase the expansion.
With divinity 2 I am having much more fun. Much more than even at the start of dao. Everyday there's a point where I say to myself "damn how can it be so good". Not only am I planning on finishing it, but also on playing FoV (which I think will like less since I've read there's no free roaming and lots of talking). And I also am already planning my second char and can't wait to start again and do broken valley from scratch
DAO may be more deep, but D2 is much more fun.
