The Dante's Inferno demo was a nasty, incoherent facsimile of an existing product, and worse, it doesn't seem to understand what makes the original worthy of emulation. I've played demos that didn't communicate the actual product before - TRON 2.0 being the most grave example - so who can say what it means for the destiny of the retail product. This demo pierced the natural curiosity that might have weakened me in a retail context, and for this I am grateful.
It did cause me to write this ridiculous poem, though:
I implored him then, saying "Apparition,
literate of that swath beyond death
give to me a portion of thy vision."
Replied my poet, with ragged breath,
"Thou must perform'st combos sweet,
'til blackest bloods water the heath
In swift rivers, dark and rising, too fast to Tweet,
Giving succor to the Tree of Skills,
where purchas'd methods do thy foes entreat
To end with haste. Cleav'd by cackles shrill,
Thy scythe does make its grim decision,
Wreath'd about in multikill."
