Disolute: I don't think you entirely got my point, although I must stress that I don't actually think Nintendo is significantly more diverse than, say, Sony. They are both diverse, but they are diverse in different ways.
Consider these two examples. Which two pairs are more diverse: Mario Golf and Mario Galaxy or Castlevania: SotN and Super Metroid?
The latter two examples have the exact same characters, virtually no storyline, but are entirely different to play. The latter two have very different characters and storylines, but the gameplay is virtually identical.
In essence, what Nintendo lacks in diversity of characters they make up for in diversity of gameplay. Some other studios have more characters but less gameplay diversity, and so forth.
