Bottomline, guys, is that Spidey is best suited for a free roam environment. And of course every free roam game is going to have linear styled missions, just like TASM will be featuring indoor stuff too. But you still have the free roam aspect when you're not on a particular mission. I don't care how good a strictly linear game can be, it doesn't fit Spidey as well as an equally good free roam game.
That being said, I think it was a smart move for Beenox to create the linear games that they did. Despite whatever criticism they may have taken for having a linear game and the 'crappiness' that gets associated with them by free roam purists, it was a necessary move IMO. I also understand that people were hating on EoT because of it's lack in quality and although I don't agree with that, I understand where it comes from.
Anyways, ever since the introduction of SM2, you had the notion that every Spidey game MUST be free roam. And while I agree that I prefer the free roam style of game, by the time WoS had been released it was apparent that the free roam games had begun to nosedive and lose their creativity. They became stale. By returning to a linear format, Beenox could channel their creativity in a new direction and for the most part it worked. Now, several years later, it's time to return to free roam. The ideas will be fresh and it feels 'new' again that we'll be free roaming around Manhattan once more.
