But you said that they were chosen to REPLACE Ice Climbers as an NES rep.
This is false. The two both being from the NES was because Retro Nintendo more or less has to be NES.
's game was also on the NES, so the "need" for any NES character isn't there.
The Ice Climbers were dropped from the work some time after spring 2014 based on an interview with Sakurai stating that Ice Climbers
were giving the team difficulty, not
had given in attempt to have them work on the 3DS version.
Sakurai also went on record that the roster was decided before development of the game was, with specific citings of
being chosen from concept art and
being changed from alternate outfits to full fighters very late in development.
