From Wikipedia: Obitus is a video game by Psygnosis, released in early 1991 for Amiga, Atari ST and DOS systems. It was also ported for the SNES, by Bullet-Proof Software. The player takes on the role of medieval history lecturer Wil Mason, whose car breaks down while he drives through Snowdonia in a storm. He seeks refuge in a deserted tower, only to wake up in a strange world.
Obitus is essentially an adventure video game, but with some arcade-style action as well. It combines several graphics styles and perspectives. It is a labyrinth game. Though nearly every piece of a forest or catacomb looks indistinguishable from the next screen, this can be dealt with by the player making physical maps, using the compass. The game is heavily focused on the need to make maps. Without them, the player will die long before making it to the end. There is very little food and time cannot be wasted walking around trying to find a way forward.
Ouch, these choices. I don't own any of these, and Obitus doesn't look like my cup of tea while the other two are stupidly expensive (for the English versions at least). I'd love to own and play Soul Blazer, but I expected it to be a $10-$20 cart tops like other Enix SNES release like ActRaiser 1/2 and Brain Lord. I voted for it, but if it wins, I won't be joining unless I can land a copy at a price I can stomach.
Not that I'll have time to join in on this one, but I'd go for Obitus, because I love old school first person Dungeon Crawlers. I actually developed mapping software for these sort of games. The only problem is Obitus is 8 directional, so Im not sure how well my software would work. I'd love to get in on this, but I've been busy working on freelance comic book art.
