Yes I have discussed it on other forums a lot. I think it came up in this forum too a long while back, but no one seemed to be interested in a discussion.
That’s probably because there isn’t really much to say about it.
It’s more a curiosity than anything else.
We could speculate a bit on what it COULD have been, but in the end it never went past a conceptual stage.
At least Van Buren got a playable vertical slice at some point.
