I cannot believe I have not heard about these games sooner.
I've been playing RPG's for over 25+ years, and have only come across these old-school gems recently.
I've played all of these: https://www.gog.com/...ster_collection
And have also played a bunch of other mainstream RPG games as well.
Bought Avernum and Geneforge complete series on GOG and started playing Blades of Avernum.
First time playing I got hooked playing it for 5+ hours non-stop.
I am looking forward to many more hours of non-stop playing of these games.
By the way...
I'm using an IE6/WinXP VM from Microsoft Tech Net under Oracle Virtual Box on a Linux Mint 17.3 install on a HP 8730w laptop.
Game is running fine - graphics/sound/mouse all work with no issues.
