Copy and pasted my response to this from another forum (lol):
I can see the plus and minus in this. The plus is that Microsoft is doing what Nintendo is doing: building exclusives so that a purchase of their system is more compelling. The minus is that Square-Enix isn't doing all that great, and limiting a franchise that not only got its start on Playstation and also isn't a top telling title against Uncharted from which the reboot draws so heavily upon (and not necessarily in a bad way, I actually LIKED the Tomb Raider reboot!) could potentially limit the sales of the game WAY more than they're anticipating.
Either way, this is both good and bad, but if the game is THAT good, Microsoft may have found their "Uncharted", and I honestly would prefer playing as Lara Croft over Nathan Drake, lol
Not quite.... Thats a false equivilence.
Nintendo (And Sony) is funding and helping to develop games that none of these AAA publishers would ever take a chance on, for the people who enjoy those kinds of games the AAA factory line refuses to make. Without Nintendo, these games would not exist. They would simply be those cancelled games that are brought up every couple of years and mourned for potential never realized.
Microsoft is taking existing games and doing nothing more than paying to keep them out of players hands on other consoles for a time proportional to the size of the money bag they crapped out.
