Super Smash Bros. for 3DS has a day 1 update, adds Conquest mode

It looks like retail version of Super Smash Bros. for 3DS will require a day-1 patch adding an additional feature to the game. The patch adds a new mode to online play called Conquest mode, which occasionally will trigger during a game and adds additional weight to the result of said match. Winning will add points to a tally that certain characters, and at the end of a certain period those points will be tallied and players associated with the winning character receive a prize.
