PixelBoy: Is this a permanent removal [...]?
I would say that this is
always anyone's guess... Having spend many,
many hours with
GOG's Community Wishlist for games I can tell you that there is absolutely no guarantee that a game will be re-distributed
anywhere.
When a studio closes down, the most likely course of action is that all of its assets will be sold. This includes licenses, publishing rights, intellectual properties, etc. If a company buys the rights to publish this game, the first thing they would want to do is to make some of that money back. Selling it in as many places as possible would seem a good way of doing so. But in the minds of some CEOs, selling a game DRM-free would invite piracy. Now, as most of the actual customers know,
DRM does not prevent piracy. Nevertheless, it appears
less likely that
Reservoir Dogs: Bloody Days would be re-released without DRM. For similar reasons, it is also less likely to ever receive any updates.
So, in conclusion: If you really want
Reservoir Dogs: Bloody Days, buy it now - because you might never get another chance. That being said, what you see is what you get. The game might never receive any
official updates to fix game breaking bugs or to run with any new operating systems. If the game can keep a fan community (or more likely a small
cult following) those fans might provide fixes. Or not.
My advice would be to read/listen to a bunch of reviews, get a good night's rest and then make a decision when you're sure about your feelings towards the game. You have 5 days, so no pressure there...
Was that answer sufficient? ;)
