Funnily enough, what that review said is basically what I said in my review about chants of shenaar, except without the glowing praise. Lots of tedious running across maps and very surface level language-puzzling, whereas I don’t remember any tedium with heaven’s vault at all. I guess different strokes for different folks?
I would say, it’s such a unique and well-executed concept that I would give it a play yourself to see what you think. It’s one of those games I haven’t found a replacement for, even with chants of shenaar.
