Will most likely be caused by fans of Sonic Frontiers and haters of the game when it comes out.
What I imagine:

Mariofan277SonicBoomsucks: This new Sonic game sucks ass, it's just a beta version of Forces. Sonic 3&K, Adventure 2, and even 06 were so much better!

BoomTTGfan!!!: The game is good, you're just blinded by your own nostalgia.

Mariofan277SonicBoomsucks: Nope, I'm just telling the truth, Sonic Boom and Teen Titans Go kiddo. You're blinded by crap. Plus you listen to Cardi B so your opinion is automatically invalid.

The only war where you, an Indian, go to fight the Germans in France, under British command, next to Moroccans and Americans. Its all because one dumbass shot another slightly less dumb dumbass and every other dumbass in Europe went apeshit, and killed more dumbasses.
"World War I is so cool! I wish we could have a field trip."

"They didn't have fields, because those dumbasses thought the other dumbest couldn't move without trees to obscure their dumbass infantry".
