Nope, I'm pretty sure it was Wizards Eye the more I think of it. And I dont think SSI did it either....(I have Wizards Crown and all three Phantasies).
Here's the story:
I was living in El Paso at the time, and my brother and I were waiting to see a movie. During this time we went to a video game store that had a special deal going on: For $5.00 you could either
a) Play as many handheld electronic games as long as you want
or
b) Get 30 min. on the Apple II computer they had setup.
Well, we choose b. And somehow the game we wound up playing was this one. Here are some more details I remember....
You had several prompts asking for your name, what type of 'body' you wanted (Also, what your body was dictated you nickname -- 'The Shadow' was mine so it was like DIRK the Shadow) The body was just the graphic of your stick figure below the head.... The Shadow was Grey, others were, say white with a cross, or some stripes, etc.
Then you had a map (I had no idea what the object was...I pretty much used up the whole half hour getting my character ready and had one fight with a bat (who killed me)....I cant really describe the map, and the screen was a B&W monitor.
I ran in to the bat and the screen changes to your stick figure on the left, and the bat on the right (jumping around)....Underneath both is just a straight line. You each took turns trying to kill each other (I remember parry, lunge -- I can see how this would sound like Phantasie but this game was long before that..)
Anyway, the game would be laughable today for sure, but looking at the Apple IIe brought back the memories. I would venture to say that this game was out around the same time as the original wolfenstien came out.....ahh memories....
