Worldwide the Super Smash Brothers series is about to become the best selling video game fighting series of all time.

Currently:

#1 - Tekken  at 47 million between all titles.

#2 - Street Fighter at 41 million between all titles.

#3 - Super Smash Bros. at 40 million between all titles pre-Ultimate.

#4 - Mortal Kombat at 35 million between all titles.

I'm a bit surprised that Tekken is ahead of Street Fighter and Mortal Kombat, I didn't realize it was that strong of a franchise.

Tekken has 7 mainline entries vs Street Fighter's 5 so that's likely why.
