After reading Sega and Nintendo's exclusive game agreement, I instantly said "NOOOO"!!!! I am absolutely shocked that Sega would make an agreement with Nintendo to make exclusive games, not that they haven't in the past, but they never formally made it official before.
This basically just tells everyone on PC, Xbox, or PS that you are not getting to play Sonic for at least two years (according to the press release). 2 years without Sonic is like an eternity!!! I don't know quite yet if this means no one but Nintendo is getting Sonic for these 2 years, because Sega always makes titles for Xbox and PS.
Why is Sega giving up on the other platforms, the next Xbox and PS4 are being released soon plus PC gaming is a big market. Nintendo monopolizes their games and content, it's exclusive to their stuff and you're not getting it if you don't have a Wii U or 3DS.
Sega giving Sonic to Nintendo is like Google conceding their market to Apple.
