So trails of cold steel on Steamspy recently passed a minor, but important milestone: It has now surpassed the number of copies sold by trails in the sky: the third. (... Assuming that variation doesn't change the numbers around a bit). For reference, it's currently 16,468 ± 3,533 copies vs 15,872 ± 3,469, but the important thing is that Trails of cold steel's audience on pc is not being limited by how many people have beaten the third.
...This may seen obvious if you even just check out the gaf OT for the game, but it's still a good sign for the series as a whole. And it's still early days for a game relying on word of mouth, too.
