I love it when games do that, personally. Particularly when each character has a unique skill that lets them access areas or scenarios that others cannot. This however can be a bit of a nightmare on the game designer's end, fair warning. The more characters to play, the more interesting the game, and more replay value is added, however designing the levels around all their unique traits without allowing any of them to "break" the intended game flow is very difficult and requires exponentially more testing. So just as a suggestion for your own sanity, if this is your first time trying something like this, I wouldn't involve more than two or three playable characters. If you want to do more than that, you can always do so in a sequel, using the first game as practice.
