arukAdo asked that I render another opinion on this front, which is as follows:
An "innovative" TAS, to me, is one which demonstrates something new/unexpected to a viewer like me who has pretty much seen everything the site currently has to offer, and, ideally, makes up a significant part of the run.
If you look at
the most recent SMW run, for example, a good chunk of the improvement arises from a single new glitch; however, much of the rest of the run is exactly what we've seen before time and time again and the run can't, as a whole, be considered too innovative. On the other hand, the
glitched SM run shows considerably different gameplay past the point of the glitch - a significant portion of the run.
I will agree, then, that the SM glitched run (for above reasons), Family Feud (tackling a new category of game), and the Chrono Trigger glitched run (for applying the relatively unexplored concept of save data corruption for massive obsolescence) can be considered innovative. I can't agree that any of the other runs mentioned here fit the criteria I had in mind, as the overall "feel" of the run compared to either their predecessors or other games of that nature isn't too out of the ordinary.
