I've purchased on GOG. Any idea what time this will launch there? They are Europe based so I guess they wouldn't have a problem launching in the morning CET?
Larian Studios just posted a global release launch with times 2 hours earlier than what Swen Vincke said in his last interview. There is no info about Steam or GOG so we can expect the release times be applicable for both. Otherwise it wouldn't have been a global launch.
That means 5pm for us living in CET.
I can confirm that it is the same release time for Steam and GoG.
I asked the GoG support and they answered that they'll release at the same time Steam does.
One caveat to GOG release is, that time only applies to Galaxy, GOG make their own offline installers, and those tend to release a few hours later. Depends on how many installers need making that day. Those of us that don't use Galaxy expect the delay.
