Undertale is going to be far weaker than last contest but that match, the loser was more 2015 than Undertale.
Rallying for a a specific game out of a year is probably far harder since you don't actually vote for that game. (also people could considere Undertale the best game ever while not considered the year as the best).

You could have bundled LoL and Melee and Starcraft in, I doubt there would have been a rally either.

And If you are talking about contest strength without rallying, Undertale is very weak but I think everyone knows it.
