Not once have I saw SB mention making modes into dlc/patch. The game can not only thrive on fighting alone or else it'll grow stale( a week of playing and bored huh?) this game combat is better than ssbb but lacks the fun. I could play ssbb without being mad and this game is annoying.
You wanted a fighting game. You got a fighting game. The three modes given are good. They are not repetitive. These "other" modes are being asked for for no reason. Look at these type of modes on other fighting games. What do you notice? NOBODY plays them often.
