If SEGA admitted that they were betraying the trust of fans, at least it means that they reflect.
As wise men says : "Do not regret. Reflect !"
As future of Sonic games, don't worry, Sonic games always sold well despite of the ratings.
I remember Aaron said Sonic Forces sold well and we know how bad the rating of that game is.
It's just hopefully that the 30th Anniversary Sonic games would be a lot better than both Mania and Forces.
Well, at least better than Forces and as good as Mania, Mania is already good.
About the future of SEGA, according to their annual reports, these three franchises alone have generated a lot profit for SEGA.
And they still have many other franchises, so the potential is still there.
So I wouldn't worry about SEGA's future.
