Not at this price. 80 bucks means the general public expect much more close to done and will not likely come back when it actually works.
Not me, but what I notice from people
No, 80 bucks means only people who are really interested in the game will get the EA and give feedback.
If the EA was free, or just less expensive, you'd have hordes of mildly curious people trying it and giving worthless feedback since they probably wouldn't play the game at release.
