Which would you prefer?
a) 5 shooters with different characters that all play the same.
b) 5 games with the same group of character that play nothing alike.

But it's not about which you would prefer. Either a game is a new IP... or it isn't.

That's where the discussion lies. ...Which one is, in fact, newer?
