Its early access, but they've ironed out many of the bugs, it runs very smoothly and its fun as hell... Yes its not real time with pause like the OG BG1 & 2... But this system works very well too and IMO is a buff to casters compared to real time with pause. I am waiting for the full release in a week. I think my first playthrough of Early access was easily 40 hours which is longer than most games and this was just act 1.
