Obitus

A history lecturer named Wil Mason has been transported to a fantasy world, ruled by four brothers. Wil's aim is to find the secret to how he was transported here and discover a way back. Obitus is an RPG with action elements. It utilizes a first-person view for exploration, similarly to Dungeon Master and Eye of the Beholder. A more remarkable feature the first-person mode: rather than having just 4 directions to choose between, there are 8, and the view scrolls smoothly. (mobygames.com)
