Hello,
I found out this post http://www.gog.com/forum/battle_isle/windows_10_cant_launch_the_game which discuss the issues of Incubation and windows 10.

I had like to extend the question to the series.
Are all games of the series incompatible with windows 10 ?
History line 14-18
Battle isle 1
Battle isle 2
Battle isle 3

My current concern is for Battle isle 3 which I started last year, but planned to continue/finish soon.
But I also planned to switch to windows 10.

Has anyone tried with a windows 7-based virtual machine ?

Is gog working on this to make it compatible with windows 10 ?
