Street Fighter 5 has gotten hit with the pain users bring when the servers not working. Errors 21400, 10007 and 2100d have been making life miserable for many players who would like to play their new game online, to the degree that Capcom producer Yoshinori Ono has issued an apology.
My sincerest apologies again about SFV server situation.
I think that we need to improve on this problem the most.Could you check @SFVServer— Yoshinori Ono (@Yoshi_OnoChin) February 16, 2016
Capcom is now reporting that the servers are back up, although users may experience intermittent disconnects. Note Ono’s use of “the most”, too: though server problems are the most frustrating problem, Street Fighter is being hammered with negative Steam reviews—54% negative, in fact. Though there’s the standard self-righteous internet rage in there, themes are emerging in the anger: the lack of DirectInput controller support; no ability to rebind keys; a perceived lightness of content.
