Hmm not sure if this was tackled (kinda skimmed through what seemed like 20 pages of platform wars and discussion if isometric camera is really needed) but there's something in that Kotaku article that bothers me more than the camera thing...
It also forced the designers into an awkward spot where they had to accommodate top-down turn-taking players and behind-the-back action-first players. By catering to the more reckless of those playing styles, the designers were forced to make the game's difficulty fairly low. Making all players play from some sort of from-the-rear camera view alleviates that.
... if the designers were supposedly forced to make the game difficulty fairly low because some players would play entirely in behind-the-back view, how is making the sequel be
all about playing from this view supposed to alleviate that? Wouldn't it rather mean the developers have even more reasons to keep the game difficulty "fairly low", because in the sequel pretty much everyone will be playing from the perspective that forced them to make the game easy in the first place?
Combined with the friendly fire being off on all but the time sink difficulty... that's rather meh.
