Only because they didn't sold gaming acessories.
What do you mean? They did sold gaming accesories years ago.
They stopped because they didn't sell well.
And the one that sold well is not even PC/console related, but mobile related one:

I find that hard to believe, I mean I don't think it was a matter of Dreamcast-era fans vs Modern-era fans. Because on the Sonic wiki I go to, Sonic Speed Sim players were dropping like flies in a zapper after the release because despite the expansions, the gameplay was disappointing for them.
I see. I don't see any rant about the gaming expansion in X and Facebook.
But then again I don't go to Sonic Wiki so I'll just have to believe what you said.
Maybe I just don't have a head for the Neptuna series.
Understandable. I only tried the games after watching the anime.
Damn, I'm like... I don't know the first thing about making a balance deck, but imagine making an all-Sonic deck and playing it competitivelky... but I dunno anything about that. Or who to "flex" towards.
I-I might buy it out of compulsion, I dunno.
Too slow, scalpers are faster than you on this one.
All well and good, but can they put their money where their mouth is? They haven't touched their old IPs in years, not even during the Sega Renaissance.
Plus, what about Dreamcast-era?
May be he only wanted to do it now? It's not like he's saying this years ago.
