Still holding out for Buck Rogers Countdown to Doomsday, it's follow up Matrix Cubed, The Dark Heart of Uukrul and Wizardry 1-5.
Yeah Buck Rogers would be a very nice surprise here.
As far as I can remember, this is one of those licensing problems issues, which GOG would probably like to see solved, and the game released, I presume, but it's not always easy.
I've seen some gameplay of Uukrul and that looked very nice as well.
At the moment I would settle for Mutant Year Zero finally arriving here, the Switch release of the game apparently is confirmed. I sent the devs a message asking about the GOG version, but I don't know if they care to comment.
