The early fighting games did not have combos but that is besides the point. Fighting games isn't about combos but the newer ones have them.
If by "newer ones" you mean "in the past twenty years" then yes. I think we should change our definition of "newer" as well.
I'm not saying there's anything wrong or bad with SSB, I love the franchise and have played all the games for more hours than I can count. But I just find it to not be a fighter and a lot of the people who say it is are honestly annoying though. There's nothing wrong with the game not being a fighter.
