Pheace: Meh, getting a super backer discount announcement after the early backer slots are already gone soured my interest, I can wait till the GOTY is on sale :)
Will probably treat it as a normal game as well. Wait till it's out, see if it's any good, and then buy it in a sale if I like what I'm reading about it. With a Q4 2019 estimated release date, it probably won't be out for about 4 years anyway (and 5 before it's reasonably bug free), and that's a long time to wait. Not like $33 (or $28) is some kind of 'steal'.
That said, I liked Wasteland 2 and it's great they plan to release Wasteland 3 too on Linux -- but I can wait. If GOG still exists DRM Free 4-5 years down the line, it will find its way here.
