Bit weird I know, but what do we think the story of Sonic 2017 will be? I know in the end, it'll be straight forward, but going by the trailer, it seems to me there's a bit more in it this time. As me and Barry previously discussed, it seems like they're going for the soft reboot like Days of Future Past with Robotnik messing with time.
I wonder if modern Sonic will have to go back and stop modern Robotnik and we'll see the previous adventures wiped away in some way. Saying that, there doesn't seem to actually be a timeline anyway.
