I like it say if the party only splits of for a little bit in the entire game, then if you get to play through each persons perspective separately for just that one stage in the game. Can't really think of any examples right now, but I have a feeling it happens quite a bit in rpgs. Playing as say ashley for a bit in rs4 also comes to mind. I also loved how the end credits of the skyward sword showed the story through zeldas perspective. Definitely a good thing to think about if it can be done well. The new fire emblem game (if?) too deals with this in quite an extreme way of having you pick one side or the other of two warring nations and playing through the entire game from that side, and having to buy the other game (or get it as dlc for cheaper) if you then want to experience the other, because of how different they two stories actually are., apparently
Agreed. The game that comes to mind right now is Seiken Densetsu 3. What I liked about it is depending on the character you pick, you go through the story differently, and the end-boss varies for which ever character you play as. As the story continues on with your choice of character, you see how it unfolds, if you didn't play as the other choices, you see how the story is different and or somehow crosses with the characters you didn't pick to begin with.
Chrono Trigger is another example, the end-game is the same, however, you can choose to go through the story how you want, with or without certain characters, or progressing in the game differently, which results in different endings.
I myself wish more games go about this path. Games that offer choice is a plus lol, you can go about it differently than the next guy, and the end-result varies for anyone who plays the game, mainly if the game has multiple endings that are good or bad (game overs).
