I wouldn't get my hopes up just yet. These could just as well be dummy entries. Some others that were discovered in the past never did make it here
Yes, there was even more than that. On official GOG Youtube channel was published trailer for XCOM2, but this trailer was removed and we still didn't got this game on GOG. :( So yes, maybe this is just some placeholders with the hope for the future. :(
Yeah I wouldn't worry (too much) about XCOM2 not showing up, things take time and maybe GOG just uploaded the video meaning to private it right away. Personally I would
be careful about AssCreed 2-3 though.
Reminder that Celeste was literally in a bunch of GOG anniversary videos.
And is nowhere to be seen.
Wasn't it given away for free by Epic Games Store? Maybe GOG opted not to release it for quite a while after learning this was going to happen. Maybe in the future, assuming it isn't given away for free elsewhere, we'll see it show up.
