Welp. Now I have to somehow convice myself that the base game is better than the long night version, since I jumped the gun and ordered that and couldn't cancel it in time.
Some reviewers do mention that in can become too convoluted for its own good, compared to the base game, so those are the kind pf reviews I'll pay attention to in order to feel better about myself.
This review for example:
"If you like the original, you'll find more of the same here and like it. If not, don't bother. If you're wondering which one to buy - if you want more complexity/difficulty buy this one and if you want more story telling w/o the complexity buy the original."
And this one:
"More Dead of Winter. Ratchets up the difficulty, which doesn't seem necessary to me, since I rarely win the base game anyways. The improvements you can build are cool, but everything else is just an annoyance. Didn't need more problems in my zombie apocalypse, needed solutions."
