There are some "patterns." The most desired character for each smash bros. game made it (Bowser in Melee, Sonic in Brawl). There is at least 2 "random" characters per game, and at least 2 "retro" characters in each game since at least Melee (note: characters can be considered both "random" and "retro").
Cracking down those patterns is harder than it seems. Look at the "retro" characters.
Who is the most popular and desired potential newcomer for Smash Bros. Wii U and 3DS=???
-Currently either Mega Man or Ridley. That can change in the future.
Who would make a good "random" newcomer character or "retro" character that follows in the style of past "random" or "retro" characters?
-Something unlike current randoms. That means probably no psychic boys (although we've gotten two!),
![Laugh :laugh: :laugh:](/styles/default/xenforo/smilies/laugh.gif)
nipple suit wearing hunk of man, duos in which you can only control one of them, a character who hasn't appeared in a game yet (like Roy), a black 2D blob, an angel, a trainer who has slave creatures,
![Chuckle :chuckle: :chuckle:](/styles/default/xenforo/smilies/chuckle.gif)
or a largely unknown robot who we all thought was a common enemy.
That could mean anything. However, all retro characters without a modern title that are playable in smash starred in at least one game.
