We have both good and bad news to share this morning, as inXile entertainment have given an update on both The Bard's Tale IV: Barrows Deep and The Bard's Tale Trilogy.
In their most recent Kickstarter update, inXile have said that progress on the massive Director’s Cut update for Barrows Deep is going really well. They said Microsoft has been a "truly amazing partner" giving them extra resources allowing them to take their time. As for the release, they're now saying it will be in "late summer" which will include the long-delayed Linux version. Hopefully those who backed it will enjoy it but it must be annoying waiting almost a year since the release for official Linux support.
As for The Bard's Tale Trilogy which was developed separately by Krome Studios, they said this:
We also have some news regarding The Bard’s Tale Trilogy for Mac gamers. Since launch, we’ve seen that Linux users have been able to play the game with minimal fuss, using methods like Steam’s Proton service. On the other hand, Mac users have not been able to play the game, so we are pleased to announce that we have made the additional investment to develop a Mac version. Krome is currently working on some additional updates for The Bard’s Tale Trilogy, and will begin work on the Mac version later this summer. All of you, Windows, Mac, and Linux, will be getting these additional Bard’s Tale Trilogy enhancement updates free of charge.
Clarifying it in the comments of the post, they confirmed "There won't be a native Linux version". It's a shame to see Linux support isn't coming for The Bard's Tale Trilogy but at least it had a "Platinum" rating on ProtonDB.
