I still play it, just not nearly as much. Most of the time I have now is spent on Injustice.
You're right about online though Vital; crazy variety online. Sometimes when I play SFxT I'll just sit in the replay section and watch top-ranked matches; its really awesome to watch. This is from my opinion, but ever since the 2013 update, SFxT players online are much better then pre-update. Idk if its because of the buffs, or if the only players left are the ones who are 100% dedicated to it.
