Super Smash Bros. began a series of games that mixes characters from several Nintendo-made games into a unique fighting game. It relies not on wearing down the opponent's "life" but increasing damage until he or she can be literally knocked off the stage. Wildly popular, this game has inspired many lazy days of casual multiplayer gaming but also intense competitive tournaments that happen to this day.
We have seen several submissions for this game here but this is the first one to be published. The author shows off fancy fighting with Yoshi on the hardest difficulty. Rather than the usual goal of speed, this movie aims to be as entertaining as possible in the tradition of all fighting games here.
Another movie, which aims for fastest completion time instead, can be watched here. There are also several other submissions and publications that can be watched on an emulator.
