Thanks to this reddit thread, here’s a look at Skyrim‘s face tech compared to Oblivion‘s and Morrowind‘s. The improvements are noticeably drastic when shown in comparison, especially the improvement in wrinkle-modeling technology. I mean, look at that Imperial’s forehead. It’s so rugged in comparison to Oblivion‘s weak, smooth foreheads.
