Linko64: As for the storefront...there's no other reason to delete non-troll reviews other than to protect profits.
While I don't like what they have done, that's not the only reason.
There is the relationship with Nightdive who may have requested the review removals, and the impact on other things if they did not oblige.
There is also the case where Nightdive may indeed have promised in private to fix the issues being complained about, and are in fact working on them right now, and almost completed them, and don't want the release marketing compromised by negatives.
As we all know, transparency is thin on the ground these days, so no real clarity.
We've already seen how rushed things can be at GOG. In this instance rushed to make the Summer Sale maybe.
P.S. I'd gotten the impression, because of the long running bad reviews at Steam, and the back story, that Nightdive would be unlikely to address the issues, but now I have read where that might be wrong, and so now I could be really pissed I did not buy the Enhanced Edition when it was 50% off.
EDIT - Without the necessary fixes being concrete though, there is still not enough reason for me to buy yet.
