I finally finished the Story Mode of Sonic Forces. Much like Sonic Mania, now that I have an informed opinion on the game, I thought it was okay. The modern gameplay feels no different from when I played Colors, and the create-a-character's gameplay is passable. A little off, but passable. With that said though, both classic Sonic and the Create-a-character didn't need to be in the game. Both of them could've been substituted with someone that's already around or completely new, and classic Sonic's gameplay just feels off in general.
As for the Story, I have mixed feelings about it. I like that it's a return to the more serious storytelling that the series has been in need of since 06/Unleashed, but at the same time, it feels like it was trying too hard to be like the Archie comics. Again, it's not perfect but it's a start that the franchise needed for years now. Enough of that depressing Sonic Boom shit.
