Competitively, this game is a flop.

Look at the activity histories of other games.
-MK7 was active til MK8 came out.
-MKW was active for a huge amount of time and died rather slowly (around 2010 activity changed hands and slowed down).
-MKDS was huge from 05-08 and has had a slower, yet steady, stream of activity since.
-MKDD may be a ghost town now but the size of the database tells a different story of the past.
-MKSC had an insanely huge non-PP player base, Japanese and North American, until about 2006.
-MK64 has never really been extremely low on activity, even 18.5 years after release.
-and SMK, after over 20 years, is still going strong.
What's the difference? Is MK8 just that 'one-too-many rehashes' game? Has Nintendo finally included enough crappy features to deter a fully-grown, long-term, competitive player base? Or, is this the start of an even newer generation of players, which will never see the glory of the classic MKs because they're too 'old'? Even dedicated MKW'ers explored games like MKSC and MK64...
