Firstly this game is based on Frostgrave. It is by no means just an out and out copy, or reskinning in a science fantasy mileu, but the rather direct lineage is pretty obvious once you get into mechanics. This is fine, originality is often completely tangental to quality. And this game is good. A strong foundation met with tinkering to make it better fit the setting. Nothing seems obviously unbalanced or unfun in the games I've played.
There used to be one rather agressive caveat, which is why this review used to be only 3 stars. Namely the font was horrible, actively painful to try and read at times.
This issue was fixed litterally the morning after I posted the original review, so the creators deserve credit for a remarkably quick response.
