I wasn't asking sources for Sonic Forces sales datas .............. "dude". I don't give a shit about Forces.Frankly dude...what sources do you have for Focres?
You know why you don't have sources? Because Sega didn't release any sources. What we have is pictures of game stores with Sonic Forces taking dust, sometimes on daily cheap discounts and not selling at all. Mania also don't have sources, but do people love to play it. Most of their fans and non fans buy it and love it, but for some reason Sega doesn't want follow up games(Taxman already said that Sega didn't reach him for more Sonic games). What more source do you want? You want Sega answering exactly your question?
It's pretty obvious. Sonic Team is on the market of main 3D Sonic games for ages. What do you think they would feel when their main game is considered a piece of garbage and a game some people offend as a "fangame" gets the better end of the stick? The only reason people even remember that crap of game is because Iizuka probably wanted Mania to reconect with the story of Forces.
