This question deals with every single genre of video games, and I want you to keep that in mind when you answer it.
How many playable characters should a game have, and why? Does the genre of a game matter when determining how many playable characters there should be, why or why not?
In RPG's the playable cast can be as small as one hero going at it on their own like in Dragon Warrior 1 or as many as over 40 like in Chrono Cross. I find that 9 or so is a reasonable cap in the RPG genre. You obviously need the basics of a hero, a love interest who perhaps might be playable, warriors, rogues, spellcasters, maybe a villain who briefly can be playable before turning heel, then throw in a couple of random others such as ninjas or summoners (these random fillers vary depending on the world the game takes place in) to make the story more interesting.
In action games you often only need one or two. One for the main storyline, with another as an unlockable mode. Devil May Cry 3 is a great example. You played through as Dante first and then Virgil was an extra mode. Zelda does fine with only Link, as do many other action/adventure games.
For Platformer games the number of characters depends on whether they get unique abilities or not. If they don't, then you do not need more than 4 so that multiplayer action can go on in the story mode. If each character has unique abilities though then a larger number can be accepted. Definitely no more than 7 if you ask me. Any number larger that would cause the developers to have to go through great lengths to make the characters different.
Fighting games can have massive playable casts, but like with platformers it comes down to the abilities. Big time. Why play a fighting game with 20+ people if they don't have abilities to set them apart? Street Fighter 4 and Smash Bros Brawl have huge lists of playable characters, and both give each person unique skill sets, justifying the number of characters you can play as. As long as the abilities set them apart enough, fighting games get away with having more playable characters than any other genre.
Racing games can have large casts too, but it ends up being rather pointless if the vehicles have stats rather than the characters. Mario Kart Wii, for instance, has a huge cast, but every single lightweight is identical to the other lightweights. As much as I love that game, that should not be the case. If the vehicles have stats rather than the characters, then you really don't need more than the 4 to 6 range. If the characters have unique stats, then much like the fighting games you can get away with having a MUCH larger cast with people that many will want to play as.
It's different for each genre, but if I had to do an overall analysis without taking genres into account, then I would go with 4 people because most genres have more than one person and if it's a one player game the other 3+ characters could always be used for unlockables or a quest with a different difficulty, and even replay value comes into the picture. 1 by themselves gets boring, with a few exceptions (Zelda) and too many people (like Chrono Cross) raises the issue of developing every single one of their stories.
So what do the rest of you think?
